Depends on the pup!! lol Sammy will put anything and everything in his mouth. That's how he "explores". When I try to take it away, he gets scared he'll lose whatever it is, so he gulps it down, making it a dangerous situation. I keep at it, though, keeping it pleasant and as if it's my right, as his 'mom' to check on anything he puts in that greedy little mouth of his. It's a work in progress..... and he's 2 1/2 .
The WORST thing I've yanked out of Sammy's mouth has got to be his frozen poop!
Though, I'm thankful it was frozen!!!
The largest thing was a raw chicken wing just last week. I feed them raw, meaty bones and he saw me approaching and instead of letting me at the bone, he tried to gulp it down in one shot. It was 90% down his throat, but I managed to grab it. He's a HOOVER!
Ricky almost never puts a thing in his mouth that isn't actual food. He'll eat any food, try any type of kibble, meat, etc.... but anything else, twigs, paper, and all that..... nope. Not interested.
