How many?

We currently have 5 dogs, although one is a puppy that I am potty/leash/basic obedience training for my grandparents.  So technically I have 4 dogs, a boxer, a doberman, a australian shepherd mix, and a dachshund.  Four dogs is definately my max, since the grandparents dog came to stay with me, my stress level has skyrocketed.  Thankfully, my grandmother should get out of the hospital on Sunday, so the pup will leave then.

Four, Two pugs, a dachshund  mix and a APBT! Love them al dearly

With that many, you must be in competitive mushing or at least actively involved in it. Being from Canada, that would make sense. I don't suppose you've ever checked out Sled Dog Central, have you?
 
Anyway, we have one dog and one cat. Jade is the cat, pure white, jade green eyes (hence, the name, thanks to some people here), about 9 months.
 
Shadow is the dog, 3 years and 4 months. Mix of Siberian Husky and Lab. 4 colors, most of them dark, though his whole look changes in winter as he grows a white undercoat. He was re-homed to us from an extremely dysfunctional family. We haven't had a chance to truly mush or even cart, but we do walk and I let him pull. With 28 dogs, you must be able to either handle them full time or bring in some help. Or are you just breeding and then the population dwindles as they are sold?
 
Something I learned along the way was the different lines of Alaskan Huskies that started with, for example the Huslia and the Aurora. Which lines do you have or are going by the lineage of winning parents? I've heard of some breeders mixing wolf in. It's about the only breeding I know of with intentional out-breeding for performance.

Just one. It's a bit cramped as it is, me, DH, baby, dog, and cat in a two bedroom apartment. I would absolutely get another dog even living here, but DH won't have it. One day, though, we plan to breed and show. I'm thinking about five, and he's thinking ten. Maybe somewhere in between, who knows.

I currently have 4 dogs, 3 Siberian Huskies and 1 GSD.  With us living on a 65 acre farm I could take on having a couple more dogs with our soon to be 3 acre yard. 

We have two and they definatley keep our hands full! I dont think I could handle anymore!

I'm at my limit of four.  I could possibly handle a foster.
