What a brill question! Really interesting too, the 'what breed would you have' topic came up on out terrier forum recently and the answers were really different!
I have three terriers and love them to bits. But I can definately see why a lot of you wouldn't have them and I would certainly not recommend them to most people! I wouldn't have a non-working type terrier like a westie or yorkie, just don't see the point of them.
Wouldn't have a toy breed, especially the teeny weeny ones you see, more rodent than dog.
Wouldn't have a bull breed. My Billy is 1/4 staffy (rest JRT) and that's as much as I will have. It's the giant heads/jaws that scare me, even though most I've met have been lovely.
I really don't like rough collies. Only ever been bitten by a dog twice and it was a RC both times! I think they have a mean look to their faces.
Wouldn't have a retriever. Grew up with them. Just not interested in having one again.
Have a soft spot for lurchers, whippets, saluki's etc. And Vislas, weimeranas and GSH pointers.
Here is the shocker....I always said I would never have a border collie! There were sheepdogs on the farm I grew up on that I didn't have much to do with, my nan had a gorgeous BC girl I grew up with and I have met many through agility, and always thought they were beautiful dogs but 'not the dog for me'. My husband wanted a collie for agility, Max is here and I take it back! He's brill! Still wouldn't be without the terriers but there's still time for Max to convince me I'm a collie girl :)
