Puppies foaming at the mouth and having spasms?

Their sugar might be low. Try giving them some karo syrup to see if that helps. I had pups that were having like seizures types but they werent bad. the vet said the sugar was low. If that doesnt help try to get a second opinion.

I'd bring them to another vet for a second opinion...A good vet would've kept them for at least the day, given fluids, done bloodwork and urinalysis...Sounds like they're having some type of seizure.

Hey-those puppies have gotten into something and ingested it. Take them to your emergency vet or back to your vet or a different vet. You just might loose all of them. Good Luck!

It doesn't sound like Rabies. They would be having issues walking and navigating the house if they did.

It sounds like they may have gotten into something like a house cleaner or something, so you either need to tell your vet to do some tests, or take them to another vet immediately.

take them back to the vet!

oh no. old yeller. rabies?

Or maybe it's allergies. Find a better vet.
