Select your new dog with your lifestyle and living situation in mind. In addition to your new family member's personality, consider its temperament, size, and coat as well. Some breeds have traits that may be objectionable in certain circumstances, such as hyper excitability or a tendency to bark. Your veterinarian is a valuable resource and should be consulted before you acquire a pet of any kind.

Breed Selection

There are two types of dogs--purebred and mixed breed. The 124 recognized breeds are grouped into seven categories: hound, working, terrier, toy, sporting, non-sporting, and herding. There are thousands of mixed-breed combinations. Each purebred or mixed-breed dog has a unique personality. Dogs originally bred for a specific purpose tend to retain these characteristics. These dogs may require additional training and patience. Selecting a specific breed does not guarantee a particular behavior, but choosing offspring from animals with desirable temperaments does increase one's chances of getting the best pet. Mixed breeds can be as beautiful, intelligent, loving, and companionable as purebreds.Veterinarians, breed-specific books (usually available at libraries and pet stores), and dog shows are excellent sources of information about individual breed characteristics and needs.

Friend or Protector?

Most dogs, even tiny ones, bark when strangers approach their home or yard. This bark is usually enough to deter intruders. A pet should not be trained as an attack dog. Attack-trained dogs require special handling and knowledge to prevent accidental injury to people, including members of your own family.

  • "We have been going to Companion Animal Hospital for over two years. The staff at Companion Animal Hospital is the most caring and considerate group of people who treats all of our "kids" like they are their own. We are very fortunate to be able to call them and have them there when we needed them. Awesome service!!"

  • "I found this place about 7 years ago when I was desperately calling around to see if a doctor would be willing to work on a Saturday to perform emergency surgery and save my pup. The receptionist called Dr. Lee and he agreed to drive back early from his church retreat for a 6 p.m. surgery ON A SATURDAY. We are in Orange County now, but we still make the drive so our sweet dog can see Dr. Lee for check-ups. I am forever grateful."

  • "A few years ago we had do put our 16 yr old Charlie to sleep because he had a stroke. They were so caring and compassionate. They gave us all the time we needed with him. Now it looks like we will need to take out 15 yr old yorkie :(. We won’t take her anywhere else."
