UPDATE! Some advice Please!!

I would try checking his mouth again. He may have a tiny piece of plastic caught in a tooth somewhere. I would wait until tomorrow to take him to the vet if he is eating and drinking but keep an close eye on him for any blood or if he starts to act funny. I know our beagles like to chew on tree branches and I don't let them do that.
I had a dog that got one caught in his mouth. It really scared me.

Maybe I'm weird, but I'd rather pay $80 to hear I'm a paranoid mom than to wait and have to fork over even more $$ to have something fixed because I waited too long. If nothing else... CALL the E-Vet, describe what has been going on and hear what they have to say. The call is free...

That's what I'd do because honestly, it sounds minor. Diane is probably right, plastic is stuck in the tooth or something. Good luck!

I called 2 different E-Vets. The first one said to bring him in right away. The second one asked questions and told me to check his mouth and the color of his gums and what to look for. The color of his gums are fine. I think he's got something stuck but he won't let me stick my hand in his mouth. I'm so confused!!
I'm going to keep trying but I'll probably end up taking him to emergency.

I'd agree with others -- rather chance $80 on Evet than $ on surgery or worse... if it were my girls, we'd already be in the car

I took him to the Emergency. They took x-rays and sedated him to do an oral exam. They couldn't find anything. They said something about acid reflux and gave him pepcid. They also gave him a shot to dry up his saliva glands for a few hours. It was a bit more than $80, but worth the peace of mind. Thank you!!

It could be that he's really sore from chewing, so he didn't want to open his mouth. But I hope the meds work!

Hoover has had acid reflux problems and did take Pepcid for a while. This could certainly be a reason for Remus' salivating. Good luck!
