Sorry, but the curiosity was killing me.
LOL!

MajesticCollies, I already saw three different vets, I posted about it here

Thank you very much for the link, I'll check it tomorrow (now it's almost midnight, and bed time). On Monday, one of our local vets will be back from vacation, he's working a lot with this holistic stuff. Earlier this year, he recommended some homeopathic remedies to treat Luna's UTIs, and it worked well. I will call him and ask him for something to boost Luna's immune system.
