What Owners Say
"Simply a great price-to-performance ratio — with the included pump dispenser no measuring is needed, and the dog eats it happily. It would be nicer in a glass bottle though, because of microplastics."

"I can't say for sure her coat is shinier, but she scratches noticeably less and the flaky skin on her rear is almost gone. Update: after 4 months of use I'm still very satisfied."
