Welcome to the forum DeeDee. You are doing a good thing in adopting rescue shelties. I never planned to adopt a rescue, but in the course of searching for a male sheltie puppy (who in time became our third dog, Figaro) I came across a little sheltie dog in dire trouble. Sooooooo....we ended up having four dogs instead of the three planned because I couldn't leave Sasha where she was. She was 12 lbs, filthy, covered in ticks, shaking and cowering, her face was raw, and she couldn't stand straight because her claws had grown into her pads.
People who mistreat animals deserve something vile....I'd love the "eye for an eye" type justice in those situations.
Other shelties end up in rescues because the dog isn't compatible with the new boyfriend, the new apartment, the new baby, or the owner has a sudden downswing in their health. These dogs are in good condition but their hearts are broken and they don't understand why their owner is leaving them.
So, I am glad to see that there are rescue angels like you out there. We have several wonderful folks like you in this forum; quietly making a difference in the world one pup at a time.
