Dpup had one for the first time late afternoon yesterday.
I noticed last night her tummy appeared bloated after she ate her dinner but put it down to gluttony.
I woke up this morning to a sick pup and 4 piles of ungodly diarrhea.
The jumbone is the only thing she had different yesterday and after a google around it appears that it's ability to make dogs ill is not uncommon.
It's safe to say she won't get another.
Be careful if giving your pups or older dogs one for the first time.
