My 6 year old Norwich Terrier started getting up early in the morning and wanting to eat grass. It started after she had a urinary infection and was given antibiotic. She needed two doses as the first one she was given didn't stop the infection. It has been two months and she she continues to eat grass about every 4 days. I have never had her wormed but checked her stool and cant see any.
Don't worry this is normal behavior in dogs. vetcare
