Irish Terrier. My last dog, Finnegan, was an Irish Terrier. It was my first experience with the breed. I had never even heard of them, prior to Finnegan!
My mom & her then-boyfriend (who were in their 70's) got him as a puppy, but then split-up when he was about 1.5 years old. I won't bore everyone with the details, but as a result of this break-up, I ended up with him. Not by default! I ADORED him, and simply announced, one day, that I wanted him, and was taking him. They were fine that. (recognized that he really should be with a younger, more active person).
Anyway.....I discovered that Irish Terriers are a GREAT breed! (Apparently they were very popular in the 40's & 50's). All the personality & energy of terriers, without the hyper-activity, and yappiness of other terriers. Smart, very sweet & loving, incredibly loyal, and very social. Got along fabulously with other dogs, of all shapes & sizes (when doggie day-care was overcrowded, they would often put him in with the room with miniature breeds, b/c even though he was 22" x 40 lbs., he played very nicely with them).
He was also a social magnet....I couldn't go anywhere (on a walk, or to the dog-park) without people commenting how cute he was! He always appeared to be "smiling" and liked strangers to pet him, etc. I met a lot of women (I'm a lesbian), simply because he was so cute & sweet!
Only drawback -- no cats! Could never have a cat with him, because he wanted to kill & maim ALL small furry creatures!! He would just go BONKERS whenever he saw a cat....or a squirrel, rabbits, etc. Maybe that would be different if he were raised with cats since a puppy? My feeling is no, since they were bred to be "ratters", in Ireland. They want to kill little furry creatures.
Other drawback....they've been so inter-bred. Finnegan was partially deaf. Hard to know if that was a result of interbreeding, or just the (bad) luck of the draw.....but, I suspect it was the former.....but it actually worked well for me, as an apartment dweller. Unlike other neighbors with dogs, he didn't bark at every sound in the courtyard. (Which endeared him to the rest of my neighbors).
I would love to have another Irish Terrier, on an IT-mix!
