My dog accidentally swallowed one of those "sticky hand toys" that come in those little plastic eggs for kids. I tried to get it out of his mouth, but he had a very strong grip on it and swallowed it. What should I do now? I read that toys can block a dog's digestive system and that it's very dangerous. What can I possibly do to prevent any painful or dangerous consequences? (This happened about 15 min. ago) Please help! I'm very worried.
