Yes they can be dog aggressive but it is more protecting what they believe is their territory. When Jack was 10 weeks old we brought him for his injections and he had a squeak not a bark and the only other dog in teh room was a St. BErnard and he decided to have a go and the vet believed that we aptly named him in his name Jack. The vet now knows him as "have a go Jack" it is an Irish saying and of course it has now stuck when we ring the vets for an appointment the girls want to know is it "have a go Jack" that they are making the appointment for.


But funnily enough he is very protective of our rescue Millie who is in the picture on my signature as he found her and will not let anything happen to her they play fight and Jack corrects her when she needs it but they are the best of friends and he will stand between her and any animal or person that we meet protecting both her and me. I love him for that.
