No two dogs are the same so I'd love to know as much information as you can give about your pets. Some things I can think of off the top of my head are: - Likes and Dislikes - Any things he/she is scared of (one of my mother's pups is a huge scaredy cat so it's good to know, just in case) - Any allergies or sensitivities - How they like to sleep (my sister's dog loves to sleep in clothes and blankets that smell like her instead of a dog bed) - How should I reward good behavior/discipline bad behavior? - Up to date on vaccinations? - What should I do in a medical emergency? I know that was a bunch of questions, but this is only to make sure I'm fully prepared, and your dog gets the best care possible. As for breed preferences, I'll accept any and all breeds, but I am a little biased to bigger dogs. They definitely have a sweet spot in my heart.
