I've got a Rott/Chow and she's got one thick coat of hair... Constantly sheading and we can never get it all out of her... It's also hot...! I've seen people do this with Newfies in the heat of summer so I'm thinking of taking it down to about a #6 1 inch cut... Her hair isn't long, med length but it's thicker than roots in a mangrove swamp... If I did it now would it grow back in time for winter...? Also, would my Walls be able to handle it or do I need a heavy duty type of trimmer for it...? What do you think...?
