Hope someone can help Weve had out BC 2 weeks now, he is fantastic in everyway....however we were told by the previous owner that other dogs dont seem to like him and he has been attacked twice (last was about 3 months ago)resulting in a vet trip. He is very good off lead where there are no dogs close by. i always put him on lead when approacing other dogs/people as we dont know how other people/dogs will be. He never barks at dogs/people just wants to sniff the occasional dog. He seems fine with other dogs when meeting when both onlead and when hes onlead and the other dogs off lead. He doesnt run after a dog he can see in the distance if he is off lead. Well anyway to the point..... i have just been to the local field playing ball with him. Little yorkie came in field on lead so called Max over and put his lead on , they had a sniff then yorkie carried on his walk and i took max offlead playing fetch again. 2 children (7ish) came over and asked if they could chuck the ball for him. Let them as i know he is fine with kids. Mean while 2 lads come on the field with a dog off lead,(i think it was a spaniel type) cant really remember. Max is quiet happiley playing with his ball.The other dog wanders over mid fetch so Max goes upto it sniffed nose to nose.....then next thig i know there fighting but not proper fighting , i had to grab max and push the other dog off him as the owner was still the other side of the field.i get max to sit and put his lead on him, whilst the other lad gets his dog. I was in shock , asks the guy if hes alright and he kept saying sorry, it was his fault. ..This makes me think the other dog might have a habit of it.....anyway Well now im doubting Max and wondering if its him that makes other dogs not like him , maybe hes not use to off lead interaction. Ive send his old owners a message asking them if use to let him play with other dogs. Now im paranoid about letting him offlead near other dogs and i know he needs to learn how to play. any sugestions?
