Since we have started discussing types of ticks and fleas are some more resistant to certain tick and flea treatments?My chow chow use to be flea free just by using the anti-flea and tick dog shampoo once every ten days as per the instructions. I would then use another type of shampoo on the other days I would give her a bath. Recently however the shampoo does not seem to work anymore and she had an infestation. I then got her a gentler tick and flea soap that the vet recommended so I could bathe her more frequently and hopefully control the infestation. That did not work so we resorted to a once a month anti-flea and tick treatment. That worked but I'm not keen on giving the dog such a powerful treatment every month as it might contain too much chemicals so I'm looking for other options.
