Red and blue dome-shaped toy, perfect for dog training. When your dog won't stop barking when left alone. A training and educational toy for puppies. Put food or small treats inside and let it roll around so they come out. They'll be so engrossed in this that the problem of barking when the owner leaves will be solved. They'll be so absorbed they won't even realize you're gone. This is how we were able to leave our dog alone. I think it's best to use it only when they're left alone. It has some scratches, but it's still usable, so I hope someone can use it for puppy training when left alone. Shipping will be via an inexpensive method like regular mail. It's about 7.7 cm in diameter. I washed, disinfected, and stored it.
