Re: 5/3 Lovey AMPS 363 =4.5 203 Not eating as well, diarrhea
I would try FortiFlora, which you should be able to buy in the vets office.
I have used Flagyl for J.D. and it worked pretty fast but would need a prescription I think.
If you haven't changed Lovey's food, I don't think I would change it now, as that may cause more diarrhea.
Make sure she is getting plenty of water so she doesn't get dehydrated.
