My dog has been sick.. for a month... temp.. lathargic... went to vet... gave meds.. no better.. today she threw up what appeared to be a large heavy mass... I think it was a stuffed toy... she was eating a lot of grass today... Is it possible that she has had this toy in her stomach for a month?. can that cause her to have a temp?. she seems a lot better now... cold nose and all... what should I do now?. thanks Leslie

Go to the vet! If your dog has been sick for a month, you should have gone back a long time ago.
