Health Considerations for Mastiffs 

mastiff health problems

Alright, let’s talk about some common food-related health problems that can crop up in our beloved Mastiffs. These big-hearted pups may be tough on the outside, but they can be sensitive on the inside when it comes to their tummies. 

Here are some food-related issues to watch out for:

  • Food Allergies: Mastiffs often suffer from food allergies. Typically, itchy skin is the most common symptom food allergies cause, so keep an eye on any coat or skin changes after trying out new foods, and consult your vet if you suspect an allergy. Often, dogs with food allergies can benefit from a limited ingredient diet (LID). 
  • Obesity: These gentle giants love their food, but too much of a good thing can lead to obesity. Extra weight can put strain on their joints and lead to other health problems. Be mindful of portion sizes and resist those pleading eyes when they’re begging for more treats!
  • Pancreatitis: Mastiffs can be at risk for pancreatitis, which is inflammation of the pancreas. Fatty foods and sudden dietary changes are known culprits. Stick to a consistent diet and avoid feeding your furry friend table scraps that are high in fat.
  • Gastritis: Mastiffs sometimes experience gastritis, which is inflammation of the stomach lining. Accordingly, it’s often wise to select very gentle foods to keep their tummies happy.
  • Joint Issues: Like many other large breeds, mastiffs can suffer from hip and elbow dysplasia, as well as arthritis. So, in addition to keeping your mastiff fit and trim, consider looking for a food with glucosamine, chondroitin, and omega-3-rich fish oils. 

Remember, our Mastiffs rely on us to make the right food choices for them. If you notice any concerning signs or have questions about your pet’s diet, don’t hesitate to reach out to your vet. Keeping an eye on what goes into your mastiff’s food bowl can go a long way in ensuring he lives a healthy and happy life!

Pet-Care Pro Tip: Watch Out for Bloat

Mastiffs are prone to bloat, also known as gastric dilatation-volvulus (GDV).

It’s a serious condition where the stomach fills with gas and twists, causing pain and potentially cutting off blood flow. It can even prove fatal, so it is definitely something you want to avoid.

Feeding smaller, more frequent meals and avoiding exercise right after eating can help prevent this scary situation.

General Food-Selection Advice & Tips

picking dog food

It’s crucial to understand that the majority of contemporary, popular dog foods are completely suitable for most mastiffs. 

However, you’ll also want to select a food that meets three mandatory criteria:

  1. Select a food for your mastiff that is specifically designed and engineered to meet the Association of American Feed Control Officials (AAFCO) nutritional guidelines. These guidelines are carefully structured and assure that the food contains all the necessary nutrients, vitamins, and minerals that your mastiff needs according to his life stage. This will ensure your dog’s health and well-being are supported as he grows and ages.
  2. Prior to deciding on a particular dog food, consult with your veterinarian. Your vet can provide expert advice based on his or her knowledge of your dog’s health history, breed-specific nutritional needs, and any potential dietary restrictions. Your vet can also help you understand the complexities of dog food labels and guide you towards choosing the best possible option.
  3. If your mastiff has any specific health conditions or concerns, it’s important to choose a dog food that caters to these needs. Dog food manufacturers often offer special formulas designed for a range of health issues, from joint problems to sensitive stomachs. By selecting a food tailored to your dog’s health condition, you can help manage his symptoms and improve his overall health.

By following these steps, it’s highly likely your mastiff will remain healthy and happy.

However, there are a few other things you can consider to ensure he’s getting the very best of the best:

  • Does the brand employ a canine nutritionist? A canine nutritionist is a professional who understands the unique dietary needs of dogs and can help formulate balanced and nutritious meals for dogs. It is important to know if such a specialist is part of the brand’s team to ensure that the dog food created is indeed nutritionally balanced and suitable for dogs.
  • How frequently does the company conduct safety inspections? Regular safety inspections are crucial to ensure that the manufacturing process is up to the standards of hygiene and safety. It also ensures that the ingredients used are fresh and free from any harmful substances.
  • Is a whole protein listed as the first ingredient in the dog food? The first ingredient listed on the packaging is the one that makes up the largest part of the food. A whole protein being listed first indicates a high-protein diet which is beneficial for dogs.
  • Are the meat meals and by-products clearly identified in the ingredient list? Transparency in ingredient labeling allows pet owners to know exactly what their pet is eating. Clear identification of meat meals and by-products will help you avoid allergic triggers and give you more peace of mind.  
  • Does the brand avoid using questionable or unnecessary ingredients? Unnecessary additives or questionable ingredients can potentially harm a dog’s health. Instead, look for foods that rely on high-quality ingredients and leave out things like artificial colors and flavors.
Pet-Care Pro Tip: Change Foods Gradually

It is crucial to change your dog’s food gradually to avoid any potential digestive upset or tummy trouble.

To transition your dog to a new food, start by mixing a small amount of the new food with your dog’s current food. Gradually increase the amount of new food while decreasing the amount of the old food over a period of 7 to 10 days.

This slow transition will allow your dog’s digestive system to adjust to the new food comfortably and healthily.
