i put sentry pro xfc on my dogs as directed for fleas .The dog started running around like the fleas were biting like crazy so i put her outside thinking they were jumping off and dieing however when i let her in we noticed excessive saliva which is only getting worse and her usual spunk isnt there! my dog is wetting every area in which it sits with saliva .I researched what could be the cause and found out other peoples pets had the same reaction to the flea medicine so i have tried washing off the medicine rinsing her mouth out with water giving her tuna juice and benadryl everything i can find that was done for the other dogs with the same reaction it's 2:00 in the morning and i have run out of things to do so keep your fingers crossed that she will make it through this !
