We adopted a lovely Springer Spaniel last week. He is absolutely wonderful with people and our resident collie. However, I am having problems with his aggression towards other dogs. He gets very excited when he sees other dogs, even at some distance - lots of lunging, crying and tail wagging. If a dog then approaches him, he goes for it and doesn't let go, even when it yelps.I spoke to his fosterer and the rescue centre and they saw no evidence of this sort of behaviour.
The poor dog has had a lot of upheaval in the past 6 weeks - dumped in an Irish dog pound, then taken to a rescue centre for 2 weeks, followed by three weeks with a fosterer (where he was very happy!), and then taken away by us. As far as I know, he has always lived in a fairly rural area. We live in London, albeit a very green part of London.
So far, I have been stopping any displays of dominant behaviour in the house (paws on surfaces and people)with a firm "paws off" and removing them. I make him sit and stay before he eats his dinner which is served after we have eaten. I make him sit and stay whilst I open the door and cross the threshold. As well as firm but kind discipline, he is getting LOADS of cuddles and love.
Exercise is a bit tricky at the moment. I need to keep him on lead because, apart from the aggression, his recall is iffy to say the least. I do what I can and run with him in the morning, have a session of clicker training in the garden and walk him for 1.5 to 2 hours in the afternoon. We are due to start obedience training in September.
Please advise me as to what else I can do to help my dog. I am at a complete loss. He has showed absolutely no aggression whatsoever towards our resident collie, so why the Jekyll & Hyde behaviour?
