I love my fur doggies. Both of mine were rescue dogs too. I want more, but I know that would not be the best right now. If I win the lottery, I'm going to give HUGE charitable donations to no kill rescues. I may even start my own. I have a huge space in my heart for dogs, and I HATE to see them living in less than desirable conditions.
We have neighbors down the street who keep their dogs outside 24/7 365 days a year. It saddens me when we have over 100 degree weather (common in Arizona) and some freezing days in the winter (we're in a higher elevation so we do get them). These dogs sleep in a hole they dug in the front yard. These idiots have their big boat and jet skies out front amongst the rest of their junk in front of their junky house, so you know what their priority is. I don't understand why they have dogs.
I have to add one more thing. I was not fond of animals until about 4 years ago. I had brought that mind-set with me from being in TWI (no pets, they smell, etc.) I didn't want a smelly dog in my house. When I got married, my husband had a chocolate lab. While I was job searching and at home, that big boy became my baby. I'm the one who let him in the house and babied him.
One dog I have now is a border collie mix, with long black hair. It gets EVERYWHERE!! But I still love her. I just vacuum more.
