Before you bring a new dog into your family with an existing dog
How you introduce a new dog (puppy) into the life of your existing dog can make or break the relationship between the two. Mature or older dogs may feel like they are being squeezed out and can quickly start resenting the new dog.
I arrange for my existing dogs to be outside when I bring the new dog home. I let the new dog walk all around the house sniffing all the scents of the household and existing dogs.
What should I look for in a vet?
The same things you would look for in a doctor for your child. Talk to your friends, family members, or neighbors who have pets (everyone has an opinion, collect some and make your own decision). Like everything else in this world there are better vets than others. You want to find one you feel comfortable with (and your puppy is comfortable with) and that you have confidence in.
Some vets specialize in certain breeds, having a vet who knows your breed of dog because they have had that breed for years may give you confidence.
