Puppy First-Year Guide

Bringing a puppy home is pure joy and a significant responsibility. At Cherry Knolls Veterinary Clinic in Centennial, we are here to help you every step of the way. Our team keeps visits calm and positive and tailors timing and treatments to your puppy’s lifestyle. Because one size does not fit all, we will personalize your puppy’s care plan after the first exam, taking into account your situation, priorities, and budget.

Bringing Your Puppy Home

The first few days at home set the tone for everything that follows. A calm, structured start helps your puppy build confidence and feel secure.

• Set up a small, quiet space with a bed, water, and a few toys before your puppy arrives.
• Keep the first day low-key. Limit visitors and allow your puppy to explore at their own pace.
• Establish a feeding schedule right away. Consistent mealtimes support house training and digestive health.
• Show your puppy where to toilet immediately after arriving and after every meal, nap, and play session.
• Keep interactions with young children and other pets brief and supervised at first.
• Schedule your first vet visit within the first week. Call (303) 779-1170 to book.

At-a-Glance Vaccine Schedule

This is our standard schedule. If your puppy is starting late or has missed a dose, we will design a catch-up plan by age. We also offer split vaccine visits for low-stress appointments.

Important Note: Lifestyle Vaccines

Vaccine choices depend on your puppy’s lifestyle, including travel, boarding, daycare, and outdoor activities such as hiking or contact with wildlife or standing water. Lifestyle vaccines such as Bordetella, Lyme, and Leptospirosis may adjust the schedule at the 12 and 16 week visits. We follow current canine vaccine guidelines and will personalize timing and product type for your dog.

Spay or Neuter

Recommendations are based on breed and expected adult size (especially large or giant breeds), sex or heat status, behavior and household goals, and current health, including umbilical hernia, retained baby teeth or malocclusion, cryptorchid testicle, orthopedic risk, and endocrine or cancer-related considerations.

For predisposed breeds we can combine surgery with OFA or PennHIP radiographs. In deep-chested dogs we can discuss prophylactic gastropexy at the time of surgery. We offer pre-anesthetic bloodwork to identify hidden issues early and support better recovery. Ask about a microchip if not already placed. Your pet goes home with a tailored pain-control and recovery plan. Home care includes an e-collar and restricted activity for 10 to 14 days.

Spay Timing (Female)

Spaying before the first heat cycle reduces the long-term risk of mammary gland tumors.

• Small and medium breeds: 6 to 9 months
• Large and giant breeds: 12 to 18 months

Neuter Timing (Male)

In a healthy male dog, delaying neutering until adult size is reached supports proper growth and musculoskeletal development. This is especially important for large-breed dogs where joint maturity plays a major role in long-term health. Your veterinarian will consider breed, age, size, and overall health to determine the safest schedule.

Nutrition for Your Puppy’s First Year

Good nutrition during the first year lays the foundation for a long, healthy life. Puppies have different energy and growth requirements than adult dogs, and choosing the right food makes a meaningful difference.

Choosing a Food

• Feed a complete and balanced puppy formula until 12 months for small and medium breeds, or 18 to 24 months for large and giant breeds.
• Large and giant breed puppies need a formula specifically designed for their size. These diets control calcium and calorie density to support steady, safe growth and reduce orthopedic risk.
• Look for an AAFCO statement confirming the food is formulated for growth or all life stages.

Feeding Schedule

• 3 meals daily from 8 weeks to about 3 to 4 months of age.
• 2 meals daily from 4 months onward.
• Avoid free feeding (leaving food available all day), as it makes house training harder and increases obesity risk.
• Always provide fresh water.

Treats and Supplements

• Limit treats to 10 percent of your puppy’s daily calorie intake. Use small, soft pieces for training.
• A complete puppy food does not need vitamin or mineral supplements unless your veterinarian recommends one for a specific health reason.
• If your puppy has a health condition, we may recommend a therapeutic diet tailored to their needs.

Foods to Avoid

• Grapes and raisins, chocolate, xylitol (found in sugar-free products), onions, garlic, macadamia nuts, raw yeast dough, and cooked bones.
• Cow milk can cause digestive upset in many puppies.

We track your puppy’s body condition score at every visit and adjust feeding recommendations as they grow. Bring any nutrition questions to your appointment.

Parasites: What to Know

Intestinal parasites are common in puppies. Roundworms, hookworms, whipworms, tapeworms, coccidia, and Giardia can cause diarrhea, vomiting, poor growth, and a pot-bellied appearance. Puppies may be infected from their mother or from the environment.

Can parasites affect people? Yes. Some are zoonotic and can infect humans. Good hygiene, regular deworming, and prompt stool clean-up protect the whole family.

Deworming and Stool Checks

• Deworming schedule: every 2 weeks until about 12 weeks, then again around 16 weeks. Higher-risk homes may continue monthly until 6 months.
• Stool tests detect parasites before signs appear and confirm successful treatment.
• First-year fecals: plan 1 to 4 tests (intake, after deworming, and again by 6 to 12 months).
• Adult dogs: yearly fecal for most, every 3 to 6 months for dogs who hunt, eat wildlife, or visit dog parks frequently.

Fleas and Ticks

Most modern preventives cover both fleas and ticks. Consistent use helps prevent tapeworm transmission via flea control and lowers the risk of tick-borne disease. Use vet-recommended prevention year-round or seasonally depending on local risk. Perform thorough tick checks after hikes or outdoor activity.

Heartworm

Heartworm is spread by mosquitoes and adult worms damage the heart and lungs. Risk varies by region, and travel changes exposure. If your puppy came from or will travel to a heartworm-endemic area, ask us about testing and prevention before travel.

Family Safety

• Submit a stool sample yearly.
• Follow deworming schedules.
• Pick up stools promptly.
• Wash hands after handling pets or soil.
• Pregnant individuals should avoid handling feces.

House Training

Keys to success include managing the environment, keeping a consistent feeding schedule, and rewarding immediately for outdoor success.

• Use a cue such as ‘Outside’ each time you take your puppy to their toilet spot.
• Watch for signals: sniffing, circling, or heading to the door.
• Interrupt gently if an accident starts. Never punish.
• Timing guideline: puppies can hold it roughly 1 hour per month of age. At 8 weeks, expect 2 to 3 hours maximum. At 16 weeks, 4 to 5 hours.
• Most puppies need to go after waking, after playing, after eating or drinking, before crate time, and at bedtime.
• Teach a signal such as sitting at the door or ringing a bell, and reward both the signal and the outdoor success.

If accidents persist, rule out a medical cause first, then refresh cues and ensure rewards happen outdoors, not back inside.

Socialization and Cooperative Care

Early positive exposure builds lifelong resilience. Aim for daily low-stress experiences during the socialization window, which closes around 12 to 16 weeks.

Socialization: Building Confidence

• Clinic happy visits to build a positive association with the vet.
• Variety of people: hats, sunglasses, uniforms, mobility aids.
• Different environments: parks, sidewalks, elevators, different surface types.
• Other dogs: limit interactions to known, vaccinated, well-mannered dogs until vaccines are complete.
• Positive-reinforcement puppy classes starting around 12 weeks with veterinary approval.

Let your puppy set the pace. Avoid flooding, forced contact, or harsh corrections.

Puppy Gentling (Cooperative Care)

Help your puppy accept handling so veterinary and grooming visits stay low-stress throughout their life.

• Keep sessions short: 60 to 90 seconds, 1 to 2 times daily.
• Touch ears, lift lips, peek at teeth, handle paws, tap nail clippers briefly, lift the tail, and practice collar grabs.
• Pair each touch with treats or calm praise.
• Practice brief stand, sit, and side-lie positions.
• Introduce soft towels on tables and low-volume clinic sounds.

Goal: a puppy who chooses to participate in handling rather than tolerating it.

Textures and Confidence Building

• Let your puppy explore grass, gravel, sand, carpet, ramps, and shallow water.
• Build a simple obstacle course at home using broom handles, cardboard boxes, umbrellas, and crinkle bags.
• Introduce one new item at a time and reward curiosity and calm behavior.

Children and Other Pets

Children

• Supervise all interactions, always.
• Allow your puppy to approach first.
• Coach gentle petting along the back or shoulders.
• Introduce one child at a time.

Existing Dogs

• Begin with parallel walks on neutral ground.
• Short, leashed on-leash meetings with positive reinforcement.
• Reward calm behavior from both dogs.
• Use baby gates or exercise pens to give each dog their own space.

Cats

• Start with scent swaps: swap bedding between pets before any face-to-face contact.
• Feed on opposite sides of a closed door.
• Use baby gates or a carrier for the first visual introductions.
• Provide the cat with vertical spaces and separate resources throughout.

Keep all introductions short, positive, and supervised. End sessions before either animal shows stress.

Foreign-Body Ingestion Hazards

Puppies explore with their mouths. Common ingested items include socks, underwear, corn cobs, cooked bones, rocks, string, hair ties, squeaker parts, batteries, ear plugs, and fruit pits.

Watch for vomiting, excessive drooling, pawing at the mouth, a tense or painful belly, lethargy, or absence of normal stools.

Do not try to induce vomiting unless directed by a veterinarian. Never pull visible string from the mouth or rectum. Call us immediately at (303) 779-1170.

Holiday and Household Hazards

The following items are toxic to dogs and should be kept well out of reach:

• Grapes and raisins
• Chocolate and caffeine
• Xylitol (found in sugar-free gum, candy, and some peanut butters)
• Onions, garlic, leeks, and chives
• Marijuana and cannabis edibles
• Human pain medications including ibuprofen, acetaminophen, and naproxen
• Rodenticides (mouse and rat poison)
• Compost and garbage
• Macadamia nuts
• Raw yeast dough

If you suspect your puppy has ingested something toxic, call us at (303) 779-1170 or contact the ASPCA Animal Poison Control Center at (888) 426-4435.

Puppy Dental and Developmental Notes

• Retained baby teeth often need surgical removal to prevent crowding and misalignment of adult teeth.
• Bite alignment issues such as narrow canines, overbite, or underbite may require intervention. We assess bite alignment at wellness visits.
• Teething: use only chews that pass the fingernail test. If the chew does not flex or dent when pressed with your fingernail, it is too hard.
• Begin gentle oral care as early as possible. Daily brushing with dog-safe toothpaste is the gold standard.
• Request a juvenile dental check at 6 to 8 months when adult teeth are coming in.

Hernias and Cryptorchidism

• Umbilical hernias may close on their own by 4 to 6 months of age or may be repaired at the time of spay or neuter.
• Inguinal hernias require veterinary assessment and are usually repaired surgically.
• Cryptorchidism (one or both testicles not in the scrotum by 6 months) requires surgical removal. Affected dogs should not be bred.

Grooming: Bonding Through Care

• Choose soft brushes suited to your puppy’s coat type and pair grooming sessions with treats.
• Use only vet-approved ear cleaners and check ears weekly for odor, redness, or discharge.
• Trim nails frequently in tiny amounts rather than waiting for them to grow long.
• Begin routine toothbrushing with dog-safe toothpaste as early as possible. Aim for daily brushing.
• Keep early grooming sessions short and positive so your puppy builds a calm association with handling.

Centennial Area and Environment Health Notes

The following conditions are relevant for puppies in the Centennial, Colorado area:

• Parvovirus: a serious, potentially fatal viral illness for under-vaccinated puppies. Avoid high-traffic dog areas such as dog parks until 7 to 10 days after the final DHPP booster.
• Kennel cough: common in shared pet settings such as boarding, daycare, and grooming. Bordetella and parainfluenza vaccines help reduce risk.
• Leptospirosis: risk increases in areas with wildlife or standing water. We vaccinate when indicated based on your puppy’s lifestyle.
• Giardia and coccidia: intestinal parasites that can cause intermittent diarrhea. Common in areas with wildlife contact or outdoor water sources.
• Heartworm: risk in Colorado is generally lower than in warm, humid states, but not zero. Dogs that travel to endemic areas or spend significant time near standing water in warm months should be assessed.
• Canine influenza: cases have been reported in the Denver metro area. Ask us about vaccination if your dog will be in high-contact settings.
• Ringworm: a fungal skin infection that presents as circular hair loss and is transmissible to people.
• Ear mites: may appear in puppies from multi-pet homes or environments with outdoor exposure.

Low-Stress Vet Visits

• Practice short car rides before the first appointment so the vehicle becomes a familiar experience.
• Bring familiar bedding or a favorite toy to the clinic.
• Ask us about pre-visit calming medications such as gabapentin or trazodone if your puppy is anxious.
• You may wait in your car before your appointment if the waiting room is stressful.
• We use cooperative handling techniques, high-value treats, and can schedule shorter happy visits between wellness exams.

When to Contact Us

Call us at (303) 779-1170 if you notice any of the following:

• Vomiting more than once in 24 hours, or any vomiting with blood
• Diarrhea lasting more than 24 hours, or diarrhea with blood
• Coughing, labored breathing, or nasal discharge
• Lethargy or significant change in energy level

Pet Insurance

Pet insurance can offset the cost of unexpected illness or injury. When comparing plans, review the following:

• Reimbursement percentage (typically 70 to 90 percent)
• Annual limits and per-incident limits
• Deductible amount (per incident vs. annual)
• Waiting periods for accidents and illness
• Pre-existing condition exclusions
• Whether the plan offers direct payment to the clinic or reimburses you after the fact
• Pre-approval requirements for major procedures

Providers available in Colorado include Trupanion, Pets Plus Us, and Fetch. Many families also set aside a monthly savings fund as a complement to or alternative to insurance. We are happy to discuss what to look for at your puppy’s first visit.
