My ACD Wicked is deep into scentwork. I found that it makes her so thirsty. So I had one of these bottles and I carry it in the big back pocket of my vest. Between searches I squeeze water out for her and now she won’t drink from anything but her bottle. She loves it, and I keep a spare in the cooler, so she always has cool water. The funny thing is all the dogs in my classes line up to get a drink from these bottles too! They have bowls on the ground but they want the squeezie water lol! So I keep Wicked’s bottle separate and carry the spare for the class dogs. Now I bought 4 more and I have plenty bottles to carry water! Best invention ever!
