Umm....I'm also not too sure myself, but I would know when I see a presence of ticks on Scottie.

Usually he wouldn't have even one on his body...sometimes every now and then maybe one or two I'm not too worried. It's when I see more than 10 ticks on his body (especially the big ones) then I roughly know it's tick season. We get it about two times a year if I remember correctly. I don't really use frontline but a lot of owners do

What I do is I would check very often on Scottie's body and if there are too many to pick off, I'll just do a tick wash (Bayticol) one time and it kind of solves his tick problem until the next season comes along

I've used Malaseb before but it was recommended by Scottie's vet though. It was when Kenji (my sister's Chihuahua who shares the same play pen as Scottie) had some fungal infection on the fur. As far as I know from the vet, Malaseb is used for the skin / coat infections, but he doesn't advise to use it very often. I only use Malaseb for Kenji once every two weeks when I see his fur dropping a lot and stop after his problem ceases. The vet very strongly advised to leave the shampoo on for 10 mins before rinsing though...he says if we leave it for less than that, the shampoo doesn't work so if you use it, make sure you leave it on for 10 mins

Well, if you think you need to change the kibbles coz the kibbles are causing the bumps, then yes. If you don't think it's the food, then maybe it's ticks or other factors (chemicals like cleaners, environment, grass seeds, etc) that could be causing the itchiness? If you could supplement with salmon oil it would be good too

Or if you can't find those, some pet shops sell the MyBeau supplement. It contains salmon oil and other stuff for the coat

I've tried that with Kenji & Scottie before and they do quite good with it too
