I followed the instruction for this and it failed it's purpose. It holds water but that's it. It's more like a punishment for my dog, have him carry this thing while walking. It gets heavy when it's filled with water. That's all it does, hold water. It doesn't cool the dog at all. I held it on my hand for a while and all I felt was like I had paper weight on my palm.
