Some foods will come down to a matter of choice and the ability of your dog’s digestive system to tolerate them. You can never go wrong by soliciting your veterinarian’s opinion.
Dogs love chewing on bones. They are mentally stimulating, they are great for a dog’s teeth, and the small bits of bone a dog scrapes off are a good source of calcium.
The issue with all types of bones is that they can splinter, cause perforation or obstruction in the digestive tract, or fracture your dog’s teeth. Most dogs should be able to digest a small amount of bone, but before allowing unsupervised consumption, you should be fully aware of how fast your dog can break into a bone. Take bones away from your dog and inspect every 15 minutes; if you notice large pieces missing or cracks in the bone, it’s time to throw it away. Do not allow your pet to gnaw bones to a size that they could swallow.
Poultry bones should be avoided because their porous nature makes them likely to splinter. Instead, look for beef marrowbones; they have a delicious center filling and the bones are thicker, so they are less likely to splinter.
Cooking destroys the structural integrity of all bones, making them more likely to fracture, so cooked bones should never be fed to a dog.
In our house, dogs get a very small splash of reduced-fat milk or plain low-fat yogurt in the morning; we call it their puppy coffee. Every once in a while, we give the dogs small pieces of cheese or scrape out the cheese grater into a lucky dog’s bowl. However, many dogs lose their ability to process lactose shortly after being weaned (just like some humans do). Our dogs consume dairy products without issue only because we keep it to a minimum. I’ve talked to many people whose dog has suddenly had a bout of diarrhea, and many times it goes back to the overfeeding of cheese. If you know your dog can eat cheese in small amounts, then it’s okay to share.
The leaves and pit of the avocado contain the toxin person, known to cause vomiting, diarrhea, and gastrointestinal irritation. The greatest concern comes from Guatemalan avocados, and less from California Hass
avocados. Avocado flesh is rich in nutrients and has essential fatty acids that can help improve your dog’s skin and coat, but excessive fat intake can cause some of the above digestive symptoms as well, so limit the amount you feed to your dog.
Whether the liver in question is beef, chicken, or something more exotic, dogs will do just about anything for the liver. The liver is rich in vitamins A and D; so rich, in fact, that it should be no more than 5 percent of a dog’s diet. This makes it better as a treat or snack rather than as a meal. Even when providing treats, do so in moderation to avoid digestive upset. Terriers, in particular, can accumulate excessive amounts of copper in their livers, resulting in hepatitis, lethargy, vomiting, and weight loss, so treats with liver should be avoided altogether for these dogs.
