There are no more fun people to talk with about dogs than horse people, and this is the best therapy ever.
I am very open but have a few deal breakers, so only fair to share them (although someone else reading this may love the suggestions that won’t work for me):
Coat - no thin coats. I live in VT and not only am not keen on dog blankets but like furry dogs. Hair, fur, double, whatever - I like dogs with their own coats. So nix the Viz and Weimaraner.
Size - 40-70 lbs (no cheating by turning a corgi into a blimp)
Barking - my barking tolerance was used up by my mother’s beloved shelties.
Prey drive actually is not a deal breaker in the right dog. The girl I just lost was an amazing and dedicated hunter. Caught an adult rabbit just last November - I was amazed. It must have been stupid. She was still perfect with cats and other dogs. Kids not so much, but neither am I.
