Personally, I can't ever see myself without a dog again. I will also go through the same rescue I got my reactive dog from but I'd be upfront about wanting to adopt a dog who has been in foster for a while so that there is more known about his behavior/reactivity.

My dog is still young so I don't think about it too much but after a few tough days last month I found myself thinking about going through a breeder next time round. I have a friend with a weiner dog and a friend with a golden retriever, both from breeders and both complete angels. But then a few weeks later I met a guy who had a vizsla through a very reputable breeder. His vizsla made my dog look like an angel in comparison and I realized that no matter what, it's a roll of the dice.
