Whether or not a dog can eat pizza crust depends on a number of factors. The most important factor of all is the ingredients used to make both the pizza and the pizza crust.
For some perspective, here are a few ingredients that may prove problematic to the dog if they snack on pizza crust.
This is the case particularly for dogs with lactose intolerance. Even that small amount of cheese stuck to the very end of the crust that you throw to your dog could trigger a reaction.
Some of the effects will include diarrhea, bloating, flatulence, and general discomfort.
It is even worse in cases where the pizza crust has been stuffed with cheese or made from dough infused with cheese or milk.
Sourdough pizza crusts could also prove problematic when consumed by dogs. For the most part, problems associated with sourdough pizza crusts occur when the sourdough is not fully cooked through.
The result is that the fermentation process will continue inside the dog’s stomach and cause great discomfort for the poor pooch.
Onions And Garlic
What is pizza sauce without a healthy dose of onions and garlic? Unfortunately, this powerful duo that gives pizza that extra kick will cause a lot of issues for your dog.
Garlic and onions are recognized as two of the most toxic foods that should be avoided in dog meals. They cause all kinds of trouble from digestive tract irritation to kidney failure.
This is probably the biggest reason why you should avoid feeding your dog pizza crust.
Oregano is pretty much synonymous with pizza and can be found not only in the sauce and as a garnish but also in the pizza crust with some recipes.
While oregano may not be super toxic to dogs, it has been known to occasionally cause gut disturbances that manifest as vomiting, diarrhea, and reduced appetite.
