Hi Lucy, I own an Irish, Olive. She is exeptionally good with other dogs, although occasionally a little submissive with dogs she knows well. However, on the occasions that she has been challenged to fight by another dog, something just comes over her and she can turn very aggressive and I know she would fight the bit out - she has left me a little unnerved at times. I would be somewhat concerned if your own dog can be a bit grumpy, as generally speaking an Irish Terrier won't back down if threatened. Olive has NEVER initiated a fight.
That being said however, Irish Terriers can be very feisty, their are nicknamed "red daredevils", as they go full throttle into situations without any regards of consequences. I have met some ITs that HATE other dogs with a vengence. I think as with most breeds if you socialise from an early age, you have a better chance of making your dog tolerate other dogs. Irish terriers are not for the faint hearted though and generally do not take well to obedience training - they are free spirits.
Also, as with all breeds, not all Irish terriers are great with people. Olive is very suspicious of strangers, particularly if I am out walking her by myself ( men are not allowed within 20 feet of me without Olive warning them off ).
If you want to discuss this more please email me at joanne@inverclydeonline.com (but be warned, IT's are my favourite subject) or join the forum as guests can only ask one question. If you email me I will also pass on details of IT related websites where you can ask all the questions you have.
Best of luck with your decision, Irish Terriers are a wonderful breed for the right person.
Joanne
