I was speaking with a sport BC breeder this weekend and after I mentioned a) I had an Aussie and b) I was concerned with potential reactivity issues in a potential future BC puppy she mentioned that she has found that BCs are much easier than Aussies (I think she'd had an Aussie and her wording was something like, "never again..."). I could see how much Aussie is quite a handful, but I sort of imagined a future BC pup to be just like her and MORE. Granted this is just one person's opinion thus far, but I'm wondering if generally the breed is a bit more difficult to manage than BCs. What are other people's thoughts and experiences? I suppose it depends on what makes a dog difficult in your eyes. Energy levels? Reactivity? (Non)-Biddability?
