Wherever you get your new puppy or dog, whether its from a breeder or a shelter, there are some physical cues you should watch for to make sure that you are getting a healthy dog:

• The dog should have a clean, shiny coat, free from rashes, bald spots, or potential parasites, like fleas and ticks.
• The dog should be in the normal weight range for this breed or mixture of dog.
• The dog should be sturdy on its feet and not limping.
• The dog should be playful and happy, not overly aggressive, or overly lethargic.
• The dog should have bright, clear, open eyes. There should be no signs of bloodshot, discharge, squinting or rubbing.

Some telltale signs that there might be a problem include:

• Thick, colored mucus drainage.
• Licking of the genital area
• Coughing
• Vomiting
• Watery diarrhea
• Excessive hair loss

Now, certainly, if you are rescuing your dog from a shelter or rescue organization, the dog may have some health issues that you will be informed of up front. The organization should be able to tell you what type of treatment might be required, and may even be able to offer discounted vet services through organizational contacts. One of the great upsides to rescuing a dog, is that you might really be able to improve a dog's life by giving it a loving home and proper treatment so that he can return to his happy self.

Of course, if you are purchasing a new puppy from a breeder, you should not accept a puppy with any of these health issues to start, for serious health issues in a brand new puppy could lead to larger problems.
