Hi friends!

Munchie is not feeling well, he start acting different since yesterday about 5 o'clock, I took him to the vet this morning.

And she told me that his "anal gland" are swollen, I felt terrible when I saw how red and a big lump he has there, she prescribe for him CLINDACURE
(CLINDAMYCIN HYDROCHLORIDE LIQUID) TWICE A DAY.
Well my question will be what can I do to prevent this to happen again?
thanks,
Gina and munchie:
