Well unfortunately it seems like it is not to be. He just rather viciously had ago at my mum's dog while i was patting her. It's such a shame he is is such a loving dog and so friendly. I hope he can find the right home.
Ah, thats a shame.
Make sure you let the people you got him from know why you are taking him back.
Jealousy is pretty common among dogs, he may have just been guarding what he thinks is "his territory" . Had the dogs met before?
