Pup Eats Pieces of Calming Collar

3 month old puppy ate a very small pice of her calming collar (tip of pinky size). She's doing everything she normally does. Should I be concerned? She hasn't vomit & stool is fine. No pieces of the object in it though.

Hello!  This sounds like a possible medical emergency and as I don't know the collar, thickness, material, or any drugs involved, this really does need to be reviewed by the emergency vet who normally looks after your dog.  In the UK, they may call the poisons / Toxins information service if chemicals have been consumed, or discuss the pros and cons of inducing vomiting in some cases.  Please do give them a call sooner rather than later in case early intervention proves necessary.  Wishing you the best of luck and please let us know how you get on.

There are no toxic substances in the collar itself. I was just wondering about the small pieces of plastic. It wasn't a lot though. Since she 3 months I was wondering. Thanks

Yes- this is definitely worth speaking to your vet about for triage.

I think the devil is in the detail regarding the size of the patient and the size of the fragments of collar, but also the material / substances involved.  Your vet is the person responsible for triage of this case.
