Also beware if you are attracted to the image of dogs portrayed on TV and in the movies. Lassie is not a real dog. She is an idealistic image portrayed by many well-trained dogs doing tricks for the camera. Likewise, when you remember the wonderful dog you had as a child, you may have forgotten a lot of the negative elements. Your new dog may not measure up to your treasured memory.
All dogs require time on the part of the owner.
They need to be walked, fed, played with, taken to the vet, and trained among many other things. As well, a dog cannot be left unattended for long periods of time on a regular basis. This means that if you work full time and cannot have someone reliable come to your house during the day, perhaps you should reconsider getting a dog. Leaving the dog in a backyard run is not an alternative as dogs need companionship and can become destructive if they are lonely or bored. Your dog will be a member of your family.
