That has happened to me a lot of times. I don't use canned dog food. I do use better grade dry food. Daisy would become Farto - the magnificent
in the presence of chicken.... either chicken bones or in dry food. If I used Costco lamb and rice or Purina Dog chow, she would have no problems. Any dog food containing chicken and you'd get a biotoxic attack.
Farting a lot means they are eating something that doesn't agree with them. Feed them something else. I've never had this be a continuing problem. Hot wing bones were the only thing that would make Daisy raid a trash can. She knew
too. I'd say "Are you FARTO?" She'd slink to the back door and wait for the storm to pass
The feed might not even have to be much more expensive. Just different. Try a different brand. I think sometimes dogs are allergic to something in a given food. Change the food, lose the farts. It's always worked for me.
One thing that can be helpful when you get a dog with a sour stomach is yogurt. Give them a cup of plain white yogurt with some oatmeal. The yogurt culture and oats settle their insides down.
In the hands of decent people, a Staffordshire Terrier is just a good sturdy dog.
I would suggest you see the whole documentary before you judge her.
Like I said, I have not seen much problem with dogs people intentionally bred. She paints this as some terrible conspiracy by Pennsylvania Mennonites to be overtly cruel to dogs in total. I don't buy it.
