So I've had Dumpling for about 2 weeks now, and I'm guessing she's probably a little over a month old. I discovered that she was in the beginning of an upper respiratory illness, so I took her to the vet. The vet prescribed antibiotics, as well as this Vitamin C liquid. So here's the problem. Dumpling is foregoing her fresh fruit and veggies for the medicine. When I give her fresh veggies (broccoli, red bell pepper, cucumber, etc), she looks at it, then raises her head and keeps squeaking. When I give her the medicine, she clamps down and refuses to let the applicator go - she's nuts over this stuff. I'm guessing the antibiotics and the vitamin C must be really really sweet. Any advice? None of my other guinea pigs ever did this before. She'll be on the antibiotic for another week. I don't think there's too much harm for one more week, but it still bothers me.
