I know that there's been discussion about it going on in a few different threads, but any chance we could consolidate it into one?

Yeah, I think that was part of why Chad didn't want a lot dog discussion in the daily hijack threads. Most of the '2 to 3' talk was scattered across those if I remember right.

Don't really remember what I said exactly, but it was along the lines of adding a third was more noticeable in cost than adding the fifth.

Was that cost food based? Equipment based (leashes, collars, harnesses, crates, etc)? Medically based (vaccinations, annual exams, flea/tick prev.)? Something else?

What about the dynamics of the '3rd wheel' with your existing pack?

That was everything based. Even a bag of carrots was noteworthy, since with two dogs, we never finished one before they molded. Changing water much more often, toys, food, vet visits... everything.

The dynamics of my pack are hard to explain. When we added the third (Coco), we already had Ridik here daily and Tambi was looking like our dog at that point. And Coco was is a major project with her aggression and tendency to not stand down. Other than her attacking others, adding more to the group never really caused any behavior problems. Oh yeah, with Jasmine here five days a week it's almost like having six. The pack dynamics I look at a little differently than others. If I want to add another dog it's not up to the dogs here already. It will happen.
