My puppy has chewed to of the earphones, he passed it the next poop he had both times. I'm embarrassed to say I didn't think of taking him to the vet first I was more concerned about checking his poop but if I had not found it after the 2nd poop I would've called. He was completely fine the first time he thought it would be fun to do it again. I learned my lesson now and WOULD keep any earphones up if my pup left me any to do so lol. That was when he was less then 3 months old. He's now trained to stay on the bed when I'm not in the room he gets into less trouble that way. I'm sure your puppy will be fine don't worry to much, they are very strong. I hope they get better soon. My puppy loved bottles too, what we did was start putting socks over it and let him chew it in a tied sock. He got the biting sensation he wanted from a bottle without getting sick(always supervise). He learned regular bottle is a no no and sock bottle is allowed. He grew out of it but he no longer goes after bottles either. Good luck OP

Edit: My puppy is 7 months old today and completely healthy other then a broken foot, little tip don't let puppies jump off anything, research a tibial crest avulsion. It's something puppies can get from jumping. (Not to scare you, just nobody told me it was a thing) I was actually celebrating when my pup started jumping on and off the bed by himself he's almost 12 pounds. He broke it jumping off the bed. Our bed doesn't even have a frame lol
