It takes a big heart to WANT to find a place in your home for an animal that may have been abused and may never be the cute cuddly animal everyone likes. Good for you!
Now I just gotta put in a plug for rescue dogs! I have had many over the years, mostly Aussies, and most I have seen or had were not abused, just neglected. Bailey, my red merle, was left behind after his "mom" divorced and spent two years in a fenced back yard. Bailey is the biggest teddy bear with melting golden/blue eyes. He loves EVERYONE and just lives to be a "good boy". With a little understanding about pack mentality, all my rescues have been "plug and play". In fact, the dog that people assume to be a rescue from abuse is Chynna, my blue merle, who hides behind my knees if people pass us on a walk. I knew when I picked her out of the litter at 6 weeks that she would be a challenge as she was hyper-suspicious of strangers even then. But she is also hyper intelligent and she has been WELL worth the effort!
To anyone thinking of getting a dog, PLEASE check out rescue dogs. They come in for all kinds of reasons, sometimes because their loving owners died. You will be able to be matched for personality, size and temperament and often skip the housetraining/chewing stage of their life.
(Thanks for the soapbox!)
