Look at him dive for that blue ball.
This canine loses all senses when he encounters a ball, of any size.
I am careful that he doesn't swallow any of his toys, in part or in whole, that would really really be bad for Joaqui.
I don't give toys that are too small or those that can easily be broken into pieces. For his teddy bears, I take of the button eyes. Final advise, do watch them at play with these things just to make sure they do not do anything harmful to themselves because of the toy.
Vomiting is a sign that they might have swallowed something (like the cotton or the threads of the stuff toy or a big chunk of their chewable bones).
