I hope this is the right place to ask this... I have a Cockapoo and she has an undercoat that is matting!! It is the strangest fur I have ever had to tend to!! I love her look and I really don't want to have to shave her... but I don't want to hurt her when I brush her!! She is brushed just about everyday!! Yesterday I put a harness collar on her to go for a long walk and when I got back it had matted her fur where it touched her chest.. UGG!! I have thought about using thinning shears to thin out her undercoat... Has anyone used shears successfully?? Any other thought would be appreciated!!!! We both THANK YOU!!
