I've gotten all my dogs' coats at Pet Smart of Petco. I don't like to spend a lot of money. The only one that didn't hold up all that well was Lyric's bomber jacket. It was not leather, but some pseudo leather and it got a few holes in it. Of course it didn't help that his big, Dober-teeth went into it at times. He would get all silly and buck, just like a horse and reach down and around...and bite his jacket. But the fleece part held up. The little dogs' jackets, I've had for a long time and they're still great. They have very cozy coats for these north Idaho winters. Toker doesn't have one. She could probably do with one. Maybe I'll get one this winter, but so far, she runs so dang hard, she doesn't seem to get cold. Then we come back inside after a bit.
But you could look online too. A lot of people love Fido Fleece. They may be pricey. Or just shop around and see what you can find locally.
When you get something, I hope we see pictures.
