I often hear people say they blow out dogs before bathing sometimes. I have never been a huge fan of this, but I will admit it does help get dander and sand out of a coat before bathing.
We do it on really rare occaisions. Twice this year in fact. BUT. Today we did use this technique.
We have a cocker named Toby who comes into the shop and he is always filthy. He is impossible to get clean no matter what we do, he always has a little bit of grey cast to his coat, and it matters not if he gets one bath or 5, he is still always dirty.
I want to add that I have always told people that IF they blow out dogs they should wear masks and goggles. WELL today that didn't happen and in the following photos you can see why I am so adamant you need to wear them to protect yourself.
He is badly sunburned from cutting grass yesterday, and he DOES have gray hair, but not THIS gray! Notice the film on the glasses and the arm of the glasses? That is DANDER from the dog.
His hand is covered in dander.
The jacket USED to be black.......
Notice all the dander on the hose? It wasn't there before he blew out the dog.
On his arm there is a lot of dander in his hair.
My theory on why this dog doesn't get clean is because the dander, that you can see there is a lot of, turns into sludge when wet. It will not wash out and it will not blow out while it is wet. It becomes almost like glue and we can comb it out while wet but it will not rinse out or wash out.
The air conditioning filter, which is outside the room by the way, is so covered in dander from this dog that I had to wash the screen and change the filter.
As you can tell, this is a dirty, messy process, but it IS effective. Just be aware that if you choose to do this you MUST take care not to breathe it in and to protect your eyes as well.
Billy said at times this felt like he was being sand blasted. The entire process took about 5 minutes to blow him out thoroughly, yet saved us about 20 minutes of bathing and extra drying time. It did take about 5 minutes to clean up.
So, yes, blowing out dirty dogs is effective. It will redue your bathing time and make the process faster.
It is however possibly dangerous and is MESSY to say the least. If the dog is on flea prevention, you are blowing pesticides all over the place. Toxins the dog ay have come into contact with are now airborne. Allergans, like grasses and weeds, are in the coat and are now in and on your skin and lungs and eyes. Its NOT a safe thing for groomers to do without proper protection. Even WITH protection I would be concerned about doing this all the time.
If you choose to do this always wear goggles to protect your eyes, masks to protect your lungs, long sleeves and pants to keep it off your skin, and a fresh smock to replace the one that will inevitably get dirty during this process. Wash your face, hair and any exposed skin after you are done.
I wouldn't make a habit of doing this in my shop, but it is another technique that has its place and will be used when needed.
