The best dog groomer in Houston even as “the best” have challenges with this furry breed. With an extra thick coat, brushing will take a while with the Sheltie breeds. There is actually a coat under a coat which is called a double coated breed. The Shetland Sheepdog is not a direct descendant of a Collie. It is a mix between smaller breeds of Scottish Collie and King Charles Spaniels. They were originally a small mixed breed but over time they developed some height. Some of the best dog groomers in Houston have an issue with these breeds because of how wiggly they are for drying with a force dryer. A force dryer is a tool that shoots warm ( not hot ) air at over 500 mph through a small 1-inch nozzle. This scares the breed a little so they tend to get a little restless and wiggly. Two products that come to mind that can help with this is Speed Dry shampoo and calming treats from thecbdfordogs.com. These two totally separate products together create a much more suitable session for both the sheltie and your groomer.
