We only adopt dogs from shelters, and have NEVER regretted it. My mom adopted a young springer spaniel with heartworms that was on the list to be killed, beautiful dog, sweetest ever too, but no-one would take her. Had her 16-17 YEARS. Second dog, 4th year of having her now. German shepherd sheltie mix, un-wanted by everyone but us. Beautiful, fluffy, sweet, and darling!!! She is now about 13. Yes, 13. We found a pure German Shepherd on January 1st. Probably dumped, because he was scared of everything. No tag, collar, or microchip, called local shelter, no one asked about him. Looked for posters in vet's office and on internet, searched area, NOTHING. He is less than 1 year old. We adopted him.
