What product would you recommend for using on dogs againsts fleas and ticks? Would only like to hear from people that live here in the D.R. and about a product can be purchased here. I have used a couple of different products but have had no luck so I would like to know which one has worked for you. I have a long haired Chow Chow and need something good enough to penetrate through his thick fur.
Many thanks.
Many thanks.
