i wonder if anyone can shed a light on my dogs behaviour, he is a 3 year old yorkie dog. last year i bought a gsd pup he was 8 weeks old so was only slightly bigger than max (my yorkie), for the 1st few days everything was fine and they played together brilliantly then on the 3rd day when the pup came to come near me max just dived on it and was attacking it, the pup had its ear ripped open although it was only a few seconds before i intervened. He had to have veternary treatment. After returning from the vets we was very watchful as any dog lover would be, max seemed pleased to see him and i gave max more attention than the pup moving away every time it came near me. That same night about 1hr after returning it happened again this time it was the pups lip that got damaged. To cut a long story short the gsd now lives with my parents and is a year old now, my question is why? i would love another dog but would never be able to have 1 while i have max. Earlier today he tried to attack my cat which is 4yr old because it came towards me, please help i'm worried in case he starts this with the children

From reading your post and without of course seeing the dogs etc, I would suggest that the problem was one of resource guarding. Dogs may guard resources - it may be a chair, a bed, a food bowl, or in some cases warmth or, very often, human affection.

Dogs can sometimes be trained out of this, but you have to take into account the dog's personality. I would suggest enlisting the help of a trainer with experience and understanding (and success in) this tupe of problem.

Hth a little :)
