Sometimes it just doesn't make sense to do a wet shave on a matted dog. If the dog is clean, it might make sense to shave first. I KNOW that comes as a shock to you since I am the "wet shave queen" but every now and then I find a dog that can be done without bathing first just as easily as it can be after the bath, and I will SOMETIMES shave first.
Meet these two poodles. They had not been groomed in almost 2 years. YES two years. Their hair was matted badly but not tight to the skin. They were clean. VERY clean. Dad had bathed them them the day before we groomed them, so they were very clean. I was able to get a 7f to go under their hair extremely easily so it worked out well.
I am not going to show you all the photos I have but a few that show how bad they were.
YES that is a lot of hair. YES those are two small poodles.
By going slow, steady and using a 7f I was able to remove these matted coats safely and easily.
Trying to decide whether or not to wet shave can be tricky. I usually only dry shave dogs that are casted, which these are not, or ones that are extremely clean, which the vast majority of dogs that need shaving due to mats are NOT.
It is very rare, but in the instances that I choose to shave dry the mats have to be far enough away from the skin that I can do a 7f or longer. I will not shave a dog with a ten or the Bravura on any setting unless I have bathed them immediatley before and they are wet. That will minimize the risk of injury and the chance of irritation as well as save your blades.
Like I said, this is an odd situation for me, but in some cases it may be to everyone's advantage to dry shave instead. Knowing when to use what technique is critical for groomers to learn. It can take years to figure out what works best for you and I am hoping I can help you get there faster with my blog posts.
