Not sure which shampoo line is GOOD, BETTER and BEST for your Pet Maltese?
Pure Paws does sell travel kits for most of their lines. The advantage of trying out the Travel Sized Kits is that you can see how much you like the line before buying larger bottles. I REGRET buying the Gallon bottles as I have given so much away == it lasts forever even if you groom a lot or have a large pack of dogs.
I recommend trying the Travel sizes as you still dilute 8:1 (Warm Water -> Product) so these travel sizes will give you ample number of shampoos to give you a good chance to evaluate the efficacy of the particular line!
Sadly the Silk Basics line does not happen to have a Travel Kit available.
