I use all the Yorkie Splash and Shine products on my Gracie. The shampoo and conditioner do not have suds like most products do because she does not use the chemical used in most regular shampoos and conditioners to make the suds and the thickening agent for the conditioner. You really don't need to make suds for the product to work properly. You just want to make sure the product goes through the fur and onto the skin distributed evenly. I always do two shampoos and then condition and get wonderful long lasting results. Some companies use a "natural" sudsing agent to make their soaps seem like the regular products but some sources question how "natural" the ingredient actually is and some say the ingredient can be a source of irritation to sensitive skin. Of course like everything else there is controversy about such ingredients. I would think that to most normal skins it would have no ill effects at all. The YSS products do not have the ingredient anyway.
When I was about to place my first YSS order I asked about getting a foaming bottle and the owner told me that they did not sell them any more because she had started to make the shampoo a bit thicker because some had complained that the shampoo was too thin. Well, I had a foaming bottle left over from something and decided to try it anyway. I found the shampoo too thick to work in my bottle so I have been using it right out of the bottle it comes in and I think it works fine. You know that all natural shampoo/conditioner for humans, WEN? It has no suds at all and people stand in the shower and pump large amounts of product into their hair to get it to work. I guess people like it because it sure is popular. My groomer used it on Gracie the last time she was there and she looked and smelled great! I have to say that the YSS products are much less expensive and easier to use!
Some people say that the foamer bottles make products go further so if you get your foaming bottle to work then you may be able to use less product. They do sell foamer bottles on ebay pretty cheap. I buy the big YSS bottles because Gracie gets a weekly bath but I think these products go a long way. Of course she is not very big so I guess it doesn't take much to get her clean.
