I have a corgi cross (not sure what the other breed is...maybe border collie.)
He is almost 3 years old.
Overall a lovely nature but for some reason(maybe because it's our first dog and we haven't trained him properly) he is extremely possessive. Today I took him to the park and he just lied on the tennis ball as if to say "Try and get it off me"..I tried but he growled and showed his teeth. This has happened several times before with toys and bones. I have been told it is dominant behaviour so maybe I should hire a dog behaviourist to fix it. Still I thought I'd try a net forum first.
We really do love our dog but we want to address this because it is getting out of hand. I'vew never seen him aggressive to other dogs or humans...but maybe if ther is a possession involved it would be a different matter.
thanks for your attention
