It really depends on the kind of toy and the size of the dog. If it was a toy that was like a stuffed animal with a squeeky thing inside, then it should be okay. If it was all plastic, like a bath toy, then (also depending on the sizes of the peices he ate) he could have some problems. if they were small peices then I wouldn't worry too much. I have a labrodor retriever that has completely digested socks, earplugs, wetwipes, and toys, and pooped them out with no problems! if your dog starts to get a hard spot on his belly or is acting unusual, you should have him checked out. I wouldn't worry though.
