Hoping for the best for Penny.
I had to have my 14 year old Black Retreiver put down a couple months back, He was very healthy for all but the last few months of his life, he was in heart failure and was going downhill. Having him put down was one of the hardest things I have ever had to do. I just couldn't stand to see him in pain anymore. He lived a good life, RIP Scout.
I do have an indoor dog, his name is Buddy and we got him from Daschund rescue 6 years ago. He is a longhaired mini. He was raised in a puppy mill that sold pups to pet shops, and when sales were slow that would also sell to the organizers of local pit bull dog fights. They would use the pups to start the fights between the big dogs... very sad.
But they got busted and we ended up with him. When we first got him he was very timid and very shy. He had never been on grass before since he was raised in a cage. But he bonded with me real quick, and when we brought him home, he knew everything was going to be ok.
Now he is one of the most laid back dogs I have ever had, he follows me everywhere without a leash, never tries to run off or go out of the yard. He is very outgoing and loves to meet anyone that comes around. He has never tried to bite anyone, even little kids that sometimes get in his face.
Here's the little couch potato in his normal pose...
