1. Digestive Issues
A dog is a creature of habit, and your digestive system would only obey the commands you give it if you feed it right. But if diarrhea, vomiting, or excess gas persist in your dogs, that might mean they are not getting along with the food you’re giving them. As stomach upsets do happen sometimes, continuous ones may just be due to intolerance to some ingredients or a need for another form of dog food.

What to do:
Visit your veterinarian for other causes to be ruled out. In case food sensitivity is suspected, a different formula with limited ingredients or specifically for sensitive stomachs might be recommended.
2. Change in Coat and Skin Condition
The coat and skin of your dog can be the most sensitive and informative sign regarding its health status. A loss of gloss and shine or excessive drying and flaking of a dog’s coat can indicate nutritional deficiency, probably with regard to the levels of omega-3 and omega-6 fatty acids in his diet. He will often exhibit continuous itching or redness on the skin and sometimes develop hot spots as well.
What to do
Look for canine food that has high healthy fats and is wheat, soy, and artificial additive-free. Quality foods contain sources of omega fatty acids such as fish oil or flaxseed.
3. Lethargy or Low Energy Levels
Energy levels among dogs vary with age and breed. However, abrupt changes in activities or excessive laziness should always raise alarm. It may result from your dog not receiving the required number of calories or possibly the fact that the current diet is not rich in nutrients for him.

What to do
Compare the calorie content and nutritional profile of the food to what your dog should have. Active breeds require a higher protein diet while older dogs are on formula diets for seniors.
4. Unexplained Weight Changes
Maintaining the right body weight is essential for any dog. You are quick to realize any form of gain or loss in your dog’s weight even when given the same portions. Such a condition has to do with their diet. The filling in the food could cause your dog to gain weight, or your dog might not be getting enough nutrients since they lose weight.
What to do:
Switch to a food more appropriate for their lifestyle, life stage, or body condition. Obese dogs may benefit from a weight management formula, while underweight dogs require higher calorie content.
5. Chronic Ear Infections
Ear infections sometimes are a manifestation of food allergies by the presence of recurring infections combined with other manifestations of allergy, such as scratching or nail licking. Common culprits include grains, chicken, and dairy products.
Action:
Talk to your veterinarian about possibly adopting a hypoallergenic or grain-free diet to alleviate frequent infections.

7. Increased Gas
Nobody enjoys a smelly dog! While some breeds are more prone to gassing, if your dog suddenly begins to emit more gas than usual, chances are that something in his food is causing him digestive upset. Common offenders include low-grade proteins, fillers, and artificial preservatives.
What to feed
Feed your canine food with wholesome, digestible ingredients such as lamb, chicken, or rice-based formulas.
8. Allergies
Some can be very subtle as well. Perhaps your dog suffers from skin issues, or conversely, she is experiencing the problem internally – digestive issues, for instance.

9. Inappetence
Dogs are notorious selective eaters, but it’s always worth an investigation if your pet suddenly stops eating something that they liked. The reason might just be that they get bored with the same old food, but it could also signal that the food has become stale or that your pet has developed an aversion because they have an undiagnosed sensitivity.

What to do
Freshness, Hydration Ensure the food is recent and fresh and is stored properly. If after trying all this, the dog remains disinterested, try offering a different flavor or brand to see if that revives interest.
10. Aging and Life Changes
Dogs mature from puppies into adults and then into seniors. So do their diets. Puppies grow fast and require food to fuel that growth. The older dogs like the joint health formulas and help prevent weight gain.
What to do:
Check the label of your dog food to ensure that it matches the life stage that your dog is in. For instance, if your dog is a puppy, adult, or senior, then look for the corresponding formula.
11. Vet Recommendations
Sometimes, your veterinarian will recommend that your dog needs a change of food because of other treatment plans due to health problems, such as kidney disease, diabetes, or urinary tract infections. Prescription diets tend to focus on targeted health problems.
What to Do
Adhere to your vet’s suggestion by gradually changing over to the food recommended in order to prevent your dog’s gastrointestinal system from protesting the switch
How to Safely Change Your Dog’s Diet
Gradual change in canine food reduces digestive problems. Mix a small proportion of the new food with the old food. Gradually introduce the ratio in increments to around 7-10 days and keep your pet under surveillance regarding discomfort and potential reactions.
