DH and I have been discussing this for a while. Talking about what our limit is for a pack to spend the right amount of time in training and such. Honestly, we said no more than 4. Ever. That may be unrealistic, as I'd like four of our own, plus one foster. For those of you who have three or four (or more!), what are your thoughts? Our plan is Boxer, American Bull, Vizsla or Catahoula, and Koolie or ACD. ACD for foster. Right now, we obviously have the ACD mix and the Boxer. The Boxer will always just be a family dog. She nor I have any interest of doing dog sports. She just doesn't care. She loves hiking and being a fool. Any sort of thing that takes work is out. Rider loves to please. And has a huge prey drive. Honestly, I think he is turning into more of my DH's dog and may become the squirrel and bunny dog he's wanted for a while. He will be gone before we get a Houla or a V (those MUST wait until we have our own set up). The bullies will stay mainly just family dogs, while the higher drives are going to be more involved in sports and such. Another thing is how many do you have in classes at one time?
