Dog Grooming Comb

- In dog grooming, will a comb attachment haircut harm a double coat like a regular blade can?
i have a pomeranian who we have shaved twice, and there is one spot that hasn't grown back normally. hair is now cotton like wooly. will a comb attachment haircut do this same harm as the blade by itself did?

A usually not. and not all dogs have a wierd reaction to a shave down, it's only once in a great while that a dog will grow back funny and even shaving the same dog over and over, just one time, it may have a funny reaction with the regrowth. over time, it may eventually grow back but yes, use a longer blade and it will have a greater chance at recovery. it is usually the 7, 10 and higher blade numbers that normally can get a wierd regrowth reaction.

- Dog grooming~?
My family found a dog out on a camping trip, we have posted flyers for the last week or so, when we found him he look really sick, emaciated, fur matted down, we cleaned him up but no one has claimed him, so we decided to keep him, he is the nicest little guy. My question is, he has a bunch of knots of fur in his under coat it's too tangled to comb out, i've tried on several occasions, we live ina relatively small town with no pet grooming places that I know of near by, so I was thinking about shaving him down almost to the skin, to try and get some of the knots out, this a good idea? anyone have a better idea? will it harm the dog in any way?

A If a dog is extremely matted, shaving is the only option. However, it *hurts* quite often. You can try it yourself, or you can ask your vet - there may be people with home-based grooming businesses in your area. Good luck, and thanks for rescuing!
