A faithful friend

This four-year-old red heeler mix is about as smart as they come. Parker may be a little leery around strange dogs, but he's as faithful a family dog as you'll hope to find. He tested as heartworm positive, so he needs to get his treatments to return to full health. But Parker is ready to be your dedicated, mellow and obedient companion. Parker is your Rockwall Adoptable Shelter Pet for the week of January 30, 2012.
