For at least the last 30 years I have had working Border Collies(and for my husband,it's probably at least twice that!). However, since my husband is starting to feel his age a bit (72), we have reduced the size of our flock and switched to mainly poultry, and I have bucket trained the remaining sheep. So, we don't have enough work for a BC, but we want another dog (our last one died last Christmas). All that's available here is BCs or Kelpies, which are arguably even less suitable for us. Even the SSPCA mostly has either sheepdogs or Staffie-type crosses, and we really want something smaller.
We are both keen walkers, and have plenty of space for a dog, but we just can't give a collie the life it needs. When I was a kid, we had a Sheltie, who was a lovely dog, although a bit...eccentric. I know there is a chance I'm looking back through a rose-tinted lens, but it feels like a Sheltie would fit. Ours had a very similar temperament to the collies I have had, but was less full-on and not nearly so prone to chewing everything if bored for a nanosecond. I know about the level of grooming and would be fine with that, but are there any potential problems that I'm missing? We have plenty of time to research breeders, and there is no hurry to decide at all, but it helps to plan ahead, because I really miss having a dog.
