i never have seen it here, in Moscow, in pet shops. we do have a big dog.But are using since many years -Killticks- also from Bayer, with no apparent harm or side effects.

after i got the article in my mail i did some digging in the internet. prices they have on ebay is just crazy. and most of it is not delivered here from the USA. and WHERE things are delivered, for the delivery charges alone, i nearly can buy the tick collar that we are using. on top of ot, i prefer to buy from -our - local pet shop, or vet clinic, supporting them,before i buy over the internet.
