I brought her to the vet and they put her on clavamox. I am just curious as to how long it normally last or until it clears up the cough. I am going to be calling my vet this morning to see if i need to bring her back in, Her clavamox is almost out. she has been on it for 5 days now i beleive. anyone had this with their pet, and how long it took to clear up? or see improvement?
