Some dogs love the crunchy sound of a water bottle in a sock or if you can sew you can make a little more elaborate stuffed critter. There are some DIY instructions out there (google something like “Crunchy Water Bottle Dog Toy”). You can buy the toys premade, but I notice they are imported. You can check those out first and just make your own. I know my puppies always loved to play with water bottles. Of course, I’m not sure where the bottles are made and the safety of them is a whole other thing.
That might work! I just made a sock toy with a tennis ball, but Linda is not amused because it doesn’t squeak. But a water bottle on the other hand makes some real good noise! I’ll try it!
