Medium Mixed Breed Dog Breed InfoEven if she’s only medium-sized, she’s got a giant heart, and she’ll give you as much love and loyalty as any big breed!

Dogs are one of the earliest species of domesticated animals, possibly even the first! Kept as companions for protection, hunting, and sociability, the ancestors of modern-day dogs helped establish themselves in the long term as man's true best friend. Believe it or not, every breed of dog today is derived from one early species of wolf! Yes, even Chihuahuas and Great Danes came from the same wolf ancestor! Over the thousands of years that dogs have lived with humans, they have been selectively bred for many different traits, such as size, intelligence, athleticism, and even just cuteness, eventually establishing all the breeds we know and love today. The downside to selective breeding can be a genetic predisposition to certain syndromes, illness, or injuries and your Mixed Breed is at risk for inherited conditions passed down from the dam and sire. Whether your pup is purebred or mixed, he's 100% dog at heart, and considering the history of the species, that's saying a lot!

Your Mixed-Breed Dog’s Health

We know that because you care so much about your dog, you want to take good care of him. That is why we have summarized the health concerns we will be discussing with you over the life of your Medium Mixed-Breed. By knowing about health concerns specific to medium-sized dogs, we can tailor a preventive health plan to watch for and hopefully prevent some predictable risks.

This guide contains general health information important to all canines as well as the most important genetic predispositions for Medium Breeds. This information helps you and us together plan for your pet’s unique medical needs. At the end of the article, we have also included a description of what you can do at home to keep your pet looking and feeling his best. You will know what to watch for, and we will all feel better knowing that we’re taking the best possible care of your pal.

General Health Information for your Medium Mixed-Breed

Dental Disease

Dental disease is the most common chronic problem in pets, affecting 80% of all dogs by age two. Dental disease starts with tartar build-up on the teeth and progresses to infection of the gums and roots of the teeth. If we don’t prevent or treat dental disease, your buddy may lose her teeth and be in danger of damage to her kidneys, liver, heart, and joints. In fact, your pet’s life span may even be cut short by one to three years! We’ll clean your dog’s teeth regularly and let you know what you can do at home to keep those pearly whites clean.

Medium Mixed Breed Dog Breed Info Infections

Medium Breeds are susceptible to bacterial and viral infections — the same ones that all dogs can get — such as parvo, rabies, and distemper. Many of these infections are preventable through vaccination, which we will recommend based on her age, the diseases we see in our area, and other factors.


Obesity can be a significant health problem in Medium Breed dogs. It is a serious disease that may cause or worsen joint problems, metabolic and digestive disorders, back pain, and heart disease. Though it’s tempting to give your pal food when she looks at you with those soulful eyes, you can “love her to death” with leftover people food and doggie treats. Instead, give her a hug, brush her fur or teeth, play a game with her, or perhaps take her for a walk. She’ll feel better, and so will you!


All kinds of worms and bugs can invade your pet’s body, inside and out. Everything from fleas and ticks to ear mites can infest her skin and ears. Hookworms, roundworms, heartworms, and whipworms can get into her system in a number of ways: drinking unclean water, walking on contaminated soil, or being bitten by an infected mosquito. Some of these parasites can be transmitted to you or a family member and are a serious concern for everyone. For your canine friend, these parasites can cause pain, discomfort, and even death, so it’s important that we test for them on a regular basis. We’ll also recommend preventive medication as necessary to keep her healthy.

Spay or Neuter

One of the best things you can do for your Medium Breed is to have her spayed (neutered for males). In females, this means we surgically remove the ovaries and usually the uterus, and in males, it means we surgically remove the testicles. Spaying or neutering decreases the likelihood of certain types of cancers and eliminates the possibility of your pet becoming pregnant or fathering unwanted puppies. Performing this surgery also gives us a chance, while your pet is under anesthesia, to identify and address some of the diseases your dog is likely to develop. For example, if your pet needs hip X-rays or a puppy tooth extracted, this would be a good time—it’s more convenient for you and easier on your friend too. Routine blood testing prior to surgery also helps us to identify and take precautions against common problems that increase anesthetic or surgical risk. Don’t worry; we’ll discuss the specific problems we will be looking for when the time arrives.

Genetic Predispositions for Medium Mixed-Breeds

Medium Mixed Breed Dog Breed InfoSuspected Disease Risks

Consider genetic testing for your mixed-breed dog because identifying your pal’s genetic make-up is an important step you can take to ensure his future health and happiness! Just because your pet might look like a Collie doesn’t necessarily mean his genes are a Collie’s! And even if your pet is part pure bred, it doesn’t mean he’ll have the same behavioral tendencies or health risks as that breed. He may have inherited traits and predispositions from his parents or even grandparents of entirely different breeds! We want to know which breeds are included in your dog’s genetic make-up so we can help you know what to expect in terms of his behavior and health.


In humans, allergies to pollen, mold, or dust make people sneeze. In dogs, rather than sneezing, allergies make their skin itchy. We call this skin allergy “atopy”, and medium-sized dogs often have it. The feet, belly, folds of the skin, and ears are most commonly affected. Symptoms typically start between the ages of one and three and can get worse every year. Licking the paws, rubbing the face, and frequent ear infections are the most common signs of allergies. The good news is that there are many treatment options available for these conditions.

  • Allergies, swimming, overgrowth of hair in the ear canals, and accumulation of earwax can all predispose your dog to ear infections, which are painful and annoying. Medium Breeds are very often afflicted by allergies, which can cause itching and inflammation in the ears and elsewhere. The earlier we diagnose and treat these ailments, the less discomfort and pain your pet will suffer. Be sure to call us if you notice him scratching or shaking his head, a foul odor from the ears, or if his ears seem painful to the touch. By monitoring for ear infections and treating them early, we also reduce the likelihood of eardrum damage that can lead to deafness. Most ear infections tend to recur until we work together to control the underlying cause.
  • Food allergies are often an inherited problem that can start at any age but tend to be most common in young adult dogs. Symptoms can include itchy skin, recurrent ear infections, and chronic vomiting or diarrhea. A prescription veterinary diet is often the best way to diagnose and treat a food allergy.


Cancer is a leading cause of death in older dogs. Your mixed-breed will likely live longer than many other breeds and therefore is more prone to get cancer in his golden years. Many cancers are curable by surgical removal, and some types are treatable with chemotherapy. Early detection is critical! We’ll perform periodic diagnostic tests and look for lumps and bumps when we examine your pet.

Medium Mixed Breed Dog Breed InfoEating Weird Stuff

In addition to the nutritious diet you provide for your pet, dogs often eat things they’re not supposed to—rocks, coins, plants, and socks, among other things. Your pet may carry an item in his mouth to check it out or play with it, or he may mistake it for food. When swallowed, these objects may become stuck in the intestinal tract and need to be surgically removed. Some plants may also be toxic to dogs. If you notice that your pet is vomiting or not acting right, call us immediately.

Heart Disease

Medium Breeds are prone to multiple types of heart disease, which can occur both early and later in life. We’ll listen for heart murmurs and abnormal heart rhythms when we examine your pet. When indicated, we’ll perform an annual heart health check, which may include X-rays, an ECG, or an echocardiogram, depending on your dog’s risk factors. Early detection of heart disease often allows us to treat with medication that can prolong your pet’s life for many years. Veterinary dental care and weight control also go a long way in preventing heart disease.

Hip Dysplasia

You’ve probably heard of hip dysplasia, an inherited disease that causes the hip joints to form improperly and leads to arthritis. Hip dysplasia is common in Medium Breeds. You may notice that your pet has lameness in his hind legs or has difficulty getting up from lying down. We’ll take X-rays of your dog’s joints to identify the disease as early as possible, and we can treat the arthritis—the sooner the better—to avoid discomfort and pain. Surgery is sometimes considered in severe and life-limiting cases of hip dysplasia. And keep in mind that overweight dogs may develop arthritis years earlier than those of normal weight, causing undue pain and suffering.

Eye Problems

Not many things have as dramatic an impact on your dog's quality of life as the proper functioning of his eyes. Unfortunately, Your dog can inherit or develop a number of different eye conditions, some of which may cause blindness if not treated right away, and most of which can be extremely painful! We will evaluate his eyes at every examination to look for any signs of concern.

  • Cataracts are a common cause of blindness in older dogs. We’ll watch for the lenses of his eyes to become more opaque—meaning they look cloudy instead of clear—when we examine him. Many dogs adjust well to losing their vision and get along just fine. Surgery to remove cataracts and restore sight may also be an option.
  • Glaucoma, an eye condition that affects many dogs and people too, is an extremely painful disease that rapidly leads to blindness if left untreated. Symptoms include squinting, watery eyes, bluing of the cornea (the clear front part of the eye), and redness in the whites of the eyes. Pain is rarely noticed by pet owners though it is frequently there and can be severe. People who have certain types of glaucoma often report it feels like being stabbed in the eye with an ice pick! Yikes! In advanced cases, the eye may look enlarged or swollen like it’s bulging. We’ll perform an annual glaucoma screening to diagnose and start treatment as early as possible. Glaucoma is a medical emergency. If you see symptoms, don’t wait to call us, go to an emergency clinic!

Patellar Luxation

Sometimes your pal's kneecap (patella) may slip out of place. This is called patellar luxation. You might notice that your pet, while running, suddenly picks up a back leg or skips and hops for a few strides. He might then kick his leg out sideways to pop the kneecap back in place. These are common signs of patellar luxation. If the problem is mild and involves only one leg, your friend may not require much treatment beyond arthritis medication. When symptoms are severe, surgery may be needed to realign the kneecap to keep it from luxating further.

Taking Care of Your Mixed-Breed Dog at Home

Medium Mixed Breed Dog Breed InfoMuch of what you can do to keep your dog happy and healthy is common sense, just like it is for people. Watch his diet, make sure he gets plenty of exercise, regularly brush his teeth, and call us or a pet emergency hospital when something seems unusual (see “What to Watch For” below). Be sure to adhere to the schedule of examinations and vaccinations that your Countryside Veterinary Clinic team recommend for him. This is when we’ll give him the necessary “check-ups” and test for diseases and conditions that are common in medium-sized, mixed-breed dogs. Another very important step in caring for your pet is signing up for pet health insurance. There will certainly be medical tests and procedures he will need throughout his life, and pet health insurance will help you cover those costs.

Routine Care

Build her routine care into your schedule to help your dog live longer, stay healthier, and be happier during her lifetime. We cannot overemphasize the importance of a proper diet and exercise routine.

  • Supervise your pet as you would a toddler. Keep doors closed, pick up after yourself, and block off rooms as necessary. This will keep her out of trouble and away from things she shouldn’t put in her mouth.
  • If she has floppy, hairy ears, clean her ears weekly, even as a puppy. Don’t worry—we’ll show you how!
  • Medium-sized dogs tend to have problems with their teeth, so you’ll need to brush them at least three times a week! And don’t let her chew on bones, ice cubes, hooves, or tennis balls either.
  • Keep your dog’s diet consistent, and don’t give her people food.
  • Feed a high-quality diet appropriate for her age.
  • Exercise your dog regularly, but don’t overdo it at first.
