Not all people qualify for a rescue animal. I didn't because at the time, I didn't have a fenced yard. Crazy, because many abused dogs are left in fenced yards unattended or tethered for days.
I would like to adopt a senior boxer, but I won't qualify for an adoption because I have an intact mastiff in my home. Go figure, my dogs are my children, never outside unattended, I cook for them, but by rescue standards I am not a good candidate.
My sister's friend's boxer passed away at the age of 13 years old (very old for a boxer), and the local rescue turned them down because their dogs are typical farm dogs, run the property, sleep in a heated barn. Some rescue groups drive people to breeders.
