Small
A little small but my dog loved them. Does not hold up to a shredder though. Perfect for typical toy lovers

None of the stuffing pulled out
I have 3 dogs. 1 is very gentle w/ stuffed toys. 1 is new to us and very anxious and kept stealing things like water bottles to gnaw on. And 1 destroys every stuffed toy we have ever brought into the house. We bought these for the anxious one. She was recently adopted and very people shy and afraid of the world around her. She doesn't know how to play with people and she's terrified if you try to throw a ball or if you squeak a squeaker, but we also needed something durable enough for her chewing that would be safe for her and could also withstand the toy destroyer possibly getting hold of it. They've been playing with these for a few months now and the most damage is that some of the rope necks are a bit frayed and a lot of the fuzz on the outside is gone, but none of them have been torn open. And the squeakers are in there in a way that it's hard to make them squeak if not doing so intentionally. The 1 dog can have plush toys again, the 1 dog can gnaw and chew to reduce her anxiety and the 3rd can chew and attack it without me having to clean up stuffing all the time
