I can't get Betsy's vet on the phone.....?

no, & if u can't get your vet, call the emergency clinic. They probaly won't help, but its worth a try. The symptoms are odd, it sounds like 2 things can be wrong. excessive salivation is a lot of times nausea, but can be a 100 other things. If your vet said use benadryl & it worked give it again again after 6-8 hours.
