“Used Virbac Hylyte shampoo first and was the best. They discontinued and so I tried Dermalyte which was recommended as comparable to Hylyte by my Vet. I love this shampoo just as much. I couldn't find it in stock for months and had to use Tropiclean Puppy Shampoo which was pretty good, but nothing beats the Dermalyte. I have two older Shihtzus who get a bath once a week and this gallon size lasts about a year.”
