Hi there. My guinea pig ( Ginger) had an upper respiratory disease. I took her to my vet 2 times gave her antibiotic for 6 days. Then I had to take her back again cos it didn't work. After that my vet told me to take her to another vet who was more specialised for small animals. He gave another antibiotic to her for another 10 days. My question is I got the probiotics ( fibreplex) which is good and my guinea loves it, so how along I have to give her now after a long time antibiotic cure? All together was like 17days. If someone can give me an answer I would appreciate it. Thanks.
