Hi, I would like to ask an advise. I suppose, my dog has SM or very similar problem. He has 9 years, he always was sensitive on his neck, which coused scratching, but nothing serious. Now it is worse - when he is on collar and leash outside, it makes him to scratch very often. So I bought harness (on photo), but there is no improvement. Is it bad type of harness probably? Do you think, that puppia would be better? And one more question - it seems, it is not only his neck, what made him to scratch, but some points about front legs or hip too - could it be in case of SM? Thank you for your reply.
