Bella ate half of a huge tennis ball from WalMart pet toys. The inside rubbery material looks and smells like salmon :roll: , but I am guessing it is some kind of rubbery substance. So she has thrown up 5 times in the past 20 minutes. There are pieces of the ball in it. I'm thinking this is good because she is getting the bad stuff out, am I right? Should I be calling the vet?
