Christmas Tree Dog Sweater

I love this hoodie. It fits her perfectly. Zoë weighs 14 pounds, is a Shih Tzu and wears a medium. Even with her harness under her hoodie, she still has plenty of wiggle room to be able to move around in it.

Not Perfect Just Pawsome Dog Hoodie

So adorable and Zoë moves in the pajamas so easily. Great for all seasons at bedtime. They keep her warm enough, but not hot so she can wear them in the summer too. Zoë weighs 14 pounds and is a Shih Tzu, wears a medium size and they fit her perfectly.
