When I was a kid I had a Husky named Sheba and Sheba's mortal enemy was the Poodle next door who the neighbours always just let out their front door and it would come over into our backyard and pee all over every little weed, flower and vegetable while Sheba watched it from inside, behind the glass patio door, and seethed. That Poodle put me off Poodles for a good long time but at some point it became obvious that stereotyping a whole breed based on the behaviour of one dog was stupid (and the behaviour wasn't really all that bad even - it just mostly pissed off my dog, and thus me by default).
But even if I had retained my negative feelings against Poodles, I think my prejudice bubble would have been burst by this guy, Berkley. I mean whatta face on him. You really just want to pick him up and squeeze and repeat. Don't do that all day, though, cuz as much as he likes the attention, you'll wear him out.
Anyway, I'm not really sure where Berkley is from but I'm thinking maybe he was owned by someone like my old neighbours, someone who opened the front door, let him out and refused to open the door for him again.
The best way to check on the adoption status of this dog (and other dogs and cats and other small domestic animals) is to visit Toronto Animal Services or call 416 338 6668 for the Toronto Animal Services South shelter.
