Tropiclean Long Hair Coat Shampoo is a shampoo intended for dogs with long coats. It is offered under the thetopdogpetstore brand listing.
Bath time used to be a wrestling match, but this lathers up fast enough that I'm done rinsing before my collie loses patience. Her long coat dried without that straw feeling, and I got a brush through the feathering on her legs way easier than usual.
My golden retriever's coat was a matted mess before I tried this, and now brushing him out takes half the time. It's made specifically for long coats, which makes a real difference compared to the regular stuff I used before. Two baths in and his fur feels softer without looking greasy.
After a single wash, my husky's long fur was noticeably softer and tangle-free—much easier to brush out. The shampoo lathered nicely and rinsed clean without leaving any residue.
