Annual Pet Care logo

Every animal is unique, and the start of each stage of life calls for different home and veterinary care. Check with your veterinarian to establish a proactive wellness plan to keep your pet happy and healthy throughout its life.

Annual Wellness

Puppies and kittens must receive a series of properly staged vaccines and physical exams. During these exams, your veterinarian may also recommend parasite preventatives or lab tests.

Adult pets will need to continue visiting the veterinarian annually for physical exams, recommended vaccines and routine testing.

Senior pets can develop similar problems seen in older people, including heart disease, kidney disease, diabetes and arthritis. Your veterinarian may recommend biannual visits to ensure your pet's quality of life.


Females spayed before their first heat cycle will be less likely to get uterine infections, ovarian cancer and breast cancer. Males neutered at any age will be less likely to get prostate disease. Spaying or neutering also helps prevent behavioral problems like marking and escaping. Talk to your veterinarian about spaying or neutering your pet.


Pets require different types of food to support each life stage. Growing puppies and kittens need more nutrient-dense food than adults while adult dogs and cats need food that will keep them healthy and energetic. Your senior dog or cat may need fewer calories, less fat, and more fiber as he or she ages. Talk to your veterinarian to determine what's appropriate for your pet.

Adult dogs should stay active with daily walks and one-on-one training. Keep your adult cats fit by using toys that encourage them to run and jump, and be sure to give them at least 15 minutes of playtime a day.

Weight management of your senior dog or cat is extremely important to ensure they are at an ideal body weight and able to move around comfortably.


Behavioral issues are a major cause of pet abandonment. Begin training your puppy or kitten right away to prevent bad habits and establish good ones.

Start house training your puppy as soon as you get home. Keep your puppy supplied with plenty of chew toys so he or she gets used to gnawing on those and not your belongings.

All cats need a litter box, which should be in a quiet, accessible room. Place your kitten in the box after a meal or whenever it appears he or she needs to go. Be sure to scoop out solids daily and empty it out completely once a week. The number of boxes in your household should be the total of number of cats plus one.

Animals age at a faster rate than humans do, and your pet's health needs will evolve over time. Use this chart to figure out your pet's age in human years, and check with your veterinarian to establish a wellness plan specific to your young, adult or senior pet.

The first warm days of the summer are officially upon us! After this past winter, we are all happy to have some better weather. During this recent early heat wave I noticed several dogs sitting in parked cars in parking lots as I ran errands around town.

Dog Panting in CarThis is common in early spring as most dogs love car trips, but gets unsafe as the summer heat arrives. This observation made me realize that it may be time to remind everyone of the dangers of leaving dogs in parked cars on warmer days any time of year.

Every year hundreds of pets are seen at veterinary hospitals as a result of heat stroke. Sadly many of these pets die from these catastrophic episodes. The worst part is that these events could be easily avoided. Cabin temperature in a car can increase by as much as 20 degrees in 10 minutes, and continues to increase as time elapses.

Leaving windows open a small amount does little to slow the rise in temperature. Dogs reduce body heat primarily by panting and perspiring through their foot pads. These are inefficient for cooling in a hot, enclosed environment. Once a dog's core body temperature increases above 105 (F), it is considered a medical emergency and veterinary care is needed.

Below is a chart that estimates a car's interior temperature increase over time:

You've just brought your healthy kitten to visit the veterinary office for her annual exam and vaccine updates. Now the vet is telling you she hears a heart murmur. How concerned should you be?

What Does That Murmur Mean?

Kitten with Muddy Creek Animal Care VeterinarianA murmur is simply a sound that tells the listener that something is causing turbulence of the blood flow as it travels through the heart.

Normally, the blood should move from chamber to chamber, and out of the heart valves, as smoothly as water running through a pipe. If something causes a partial blockage, if there's a leak in the system, or even if the liquid isn't being propelled efficiently, turbulence will result in the sloshing sounds we refer to as "murmurs" when we speak of heart function.

In kittens and young cats, congenital irregularities of the heart can cause these sloshing sounds. The majority of these are "innocent" murmurs that will resolve as the patient grows and its heart matures.

Persistent or loud murmurs, however, can be secondary to more severe defects and should be investigated if accompanied by any weakness, pallor, shortness of breath, failure to grow or thrive, or if they persist until the time the pet is due to be spayed or neutered.

Our team of caring professionals is devoted to you and your pets!
