My female pup had a case of puppy vaginitis when she came home which apparently is not too uncommon. She did some licking and tried peeing often to relieve the itching so it could be that rather than uti. She also had giardia at the same time. They some time will get hit with double and triple whammies at that age. If she doesn't continue to do well on the chicken you might try cooked ground beef since some dogs don't tolerate chicken well- my male for instance. Offer her some Gatorade as well as the water, mine sucked it down while being treated then stopped when it wasn't needed anymore. Sounds like your girl is going the right direction with the treatments- we've all gone through the multiple health problems all at once with our new little ones.
