Yes, I have.

About 4 different litters of dogs that I fostered for the humane society when I volunteered there.
Another litter for a neighbor who took in a stray lab that showed up pregnant. The dog got out of the back yard while she was out going potty and got ran over the day she had her puppies, so I offered to bottle feed them for them. They lived with me until they were 8 weeks old, and then I found wonderful homes for both of them.
3 baby kittens.
A litter of baby rats, but only 2 of them made it.

A.J. our pit bull/boxer/? mix was bottle fed from the day she was born until she was 5 weeks old. She is 10 months old now.

I also bottle fed a newborn chihuahua that was the runt of a friends litter. The mom wasn't feeding her, and was pushing her away. She weighed 2 oz. when we got her at 2 days old. She only lived 3 days after we had her though.
