Spot on? Let it dry!
Pet owners will be familiar with spot-on treatments for a variety of parasites, including fleas, ticks and lungworm. Products are regularly issued by pet shops as well as veterinary practices, with versions available for both cats and dogs.
Although we are not aware of any Orchard clients having had problems, we do know that some unfortunate pet-owners have found stains on soft furnishings, including leather, after applying spot-on treatments - their pets having transferred the product before it had dried.
As with all drugs, spot-on treatments are combined with other chemicals to allow them to come into contact with the body of the animal without causing a reaction, usually an alcohol-type solution such as benzyl. Such solvents may damage certain materials including leather, fabrics, plastics and finished surfaces. An analogous product would be nail varnish remover - entirely harmless on your skin, but it won't do a polished wood surface any good!
Clients are therefore reminded to allow the application site to dry before permitting contact with such materials - including car interiors and collars. §
