Hi everyone, I haven't been on YT in a very long time....nice to be back. Unfortunately I am having a simultaneous issue; I have 3 yorkies 7 pounds and under, 2 of the 3 have bouts with pancreatitis on occasion. They have been besieged by fleas and the topical stuffs a waste of money as it isn't working at all. My vet wants to try comfortis....my gut tells me NO. I don't know what to try next. I get my yard/house sprayed, bathe them with a special shampoo coz they have skin issues and dawn irritates them something fierce, have and continue to get all bedding washed. Still the lil buggers persist! So...I realize there is a lot of issues at once so Ill narrow it down;
1. how do I prevent tummy issues all together (they are on Purina one, which has worked for over 2 years)
2. how do I get rid of the pests without harming my fur babies?
Any suggestions welcome.
