I am a frequent user of Pinterest and on there I found the best thing. All you have to do is get some treats or toys for your dog. Then you can fill up some sort of piece of Tupperware to put those treats in along with some water. Then you just want to freeze it overnight. I did this for my dog Remy and he loved it. It was great watching him trying to get the treats and the toys out that was in it. I put a dinosaur toy in and a couple of treats. I tried to upload a photo of my dog and the ice block of treats, but the file was too big. I attached a photo of someone else's pug that they did the same thing with. Do you guys do anything like this with your dogs?
