Ever gazed into your pup’s eyes and wondered how many years they have left? If so, you are not alone. For owners of medium-sized dog breeds, you’re in the sweet spot. These medium-sized dogs enjoy a nice balance between the longer lifespans of smaller dog breeds and the big personalities and playfulness of large breeds.
But, how long will they live, and what can you do to support your dog’s ability to age healthfully? You’ve come to the right spot for these answers.
Let’s talk about your medium-sized dog and how to help them live the longest, healthiest life possible.
What Is a Medium-Sized Dog Breed?
Dog breeds are usually categorized by size. Sizes include toy, small, medium, large, and extra large (or giant). Medium-sized dog breeds usually weigh between 25 and 50 pounds when they are fully grown.
Medium-sized dogs include cocker spaniels, border collies, bulldogs, basset hounds, and many more. These breeds are known for being energetic, sturdy, and overall good fits for families and individuals.
How Long Do Medium-Sized Dogs Live?
A well-cared-for medium-sized dog can live between 10 and 15 years or longer. This is just a median life expectancy. Genetics, lifestyle, breed, and health conditions can all stretch or shrink that number. Some breeds are prone to certain health risks that can reduce their lifespan, while others have fewer health risks and enjoy an overall better shot at hitting that 10-to-15-year mark.
Factors That Affect Your Dog’s Lifespan
Every dog is different, but several common factors play a role in how long your dog will live. While you cannot change your dog’s genetic makeup, you can ensure they are properly cared for, and that goes a long way in terms of your dog’s lifespan.
1. Genetics
Your dog’s DNA, like yours, plays a role in their longevity. Breeds that have historically been strong, working dogs (like the Australian Shepherd) tend to enjoy slightly longer lives than breeds that are built purely for aesthetics and showing.
The breed of dog you choose makes a difference when it comes to a longer life. On average, the smaller the dog, the longer the lifespan.
2. Spaying and Neutering
Dogs that are spayed and neutered live longer than dogs that are not. Dogs that are fixed are less susceptible to certain types of cancers and are also less prone to engage in dangerous behavior. Many animal shelters offer spaying and neutering services at a discount, allowing all pet owners the opportunity to make this decision for their pets.
3. Lifestyle
Dogs that are happy, well-loved, and get plenty of exercise live longer than dogs that are neglected. Keeping your dog mentally stimulated, feeding them high-quality food, and ensuring they get preventive care from their veterinarian can add years to your dog’s life. In addition, forming a close, trustworthy bond with your dog can help them live a happier life as senior animals.
Knowing what kinds of problems could harm your dog is just as important as ensuring you are giving them proper care.
Common Problems for Medium-Sized Dog Breeds
Some health conditions pop up more in medium-sized dogs than in small dogs or large dogs. If you have these on your radar, you can stay a step ahead in your dog’s care.
- Joint problems. Although medium breeds don’t suffer as many joint problems as large dogs, they can develop arthritis and hip dysplasia, especially as they age.
- Heart disease. Some medium breeds are prone to heart disease (like mitral valve disease). If your dog develops a cough or fatigue, they should see their veterinarian immediately.
- Obesity. Obesity can cause a lot of problems for medium-sized dogs. Excess weight places a strain on their joints and organs. Keeping a healthy weight is important.
- Dental disease. Dental disease is common among medium-sized breeds. Left untreated, it can lead to tooth loss and even systemic illness and death.
While these health concerns can be serious, these breeds are known for their resilience. Some even tend to outlive their expected lifespans, giving their owners more years of tail wags.
Medium Breeds Known for Long Lives
Whether you are looking for a new pet to love or already own a medium-breed dog and want to know how long they’ll be around, we’ve got the scoop on several medium breeds known for their ability to beat the odds and outlive their peers.
Australian Cattle Dog
The longest-living medium-breed dog is the Australian cattle dog. In fact, the world record for oldest living dog goes to an Aussie cattle dog named Bluey who lived to be 29 years and five months old. These dogs are built tough, energetic, and expected to live between 15 and 19 years.
Beagle
If you were looking for a classic, fun-loving family dog, the beagle will not disappoint. Get a beagle when your kids are born, and they can theoretically help you see them off to college. Beagles have a lifespan of between 15 and 18 years, which means your dog can grow up right with your children.
Border Collie
If smarts is a quality you want in a dog, the border collie is your go-to. These dogs, known as the Einsteins of the dog world, are sharp and energetic. Their mental acuity is likely a key component of their ability to live long (and prosper). Border collies have a life expectancy of between 12 and 16 years.
No matter which breed you have, there are steps to take to give your dog the best chance of reaching their expected lifespan.
Preserving Your Dog’s Lifespan
You play a major role in your dog’s ability to live a longer life. By taking care of your dog’s health, you can stack the odds in their favor and help them live healthfully into their senior years.
- Give them healthy kibble. Not all kibble is created equally. Skimp on their diet and they could miss vital nutrients they need to thrive.
- Ensure plenty of exercise. All breeds need exercise, and medium breeds need a good amount of exercise and outdoor play to thrive.
- Get preventive care on the books. If it’s been a while since your dog has seen their vet, get an appointment scheduled asap. Preventive care can rule out illness and protect against it.
- Consider a supplement. Longevity15 is a once-per-day supplement that helps support your dog’s cells (the very foundations of their health). It promotes healthy heart, liver, and red blood cell function and even helps with glucose handling.
Taking care of your dog and giving them Longevity15 once daily is a smart way to support your furry friends and give them the best chance of living the longest life possible.
