Here are a few tips that should make his life and yours easier.
First, if you don't have time to comb him to the skin, don't bathe him! Washing a
tangled dog or cat will have the same effect as washing a woolen sweater in hot water!
The tangles shrink and tighten as they dry. Before his bath, brush and comb him
to the skin. Concentrate on chest, belly and "armpits," where friction and wet
grass cause the most tangling. Check with a fine comb under his collar and right
behind his ears. These areas tend to tangle too.
Ask your groomer to show you the correct combs and brushes to use. Use products
made for your pet, often over the counter shampoos can be harsh and drying to
your pet's hair.
Remember your groomer would much rather groom a happy mat free pet than one that
is miserably tangled and thinks groomers are bad guys....because they pull his hair!
