what breed do you think this dog is I got him Friday. tried to brush him but he's full of knots the family I got him off said they didn't have time to groom him due to working all day ( he's a right mess poor dog) he's going to the groomers tomorrow.looks like he may have to be shaved ☹️he's 19 months old.hes really good hasn't messed in the house once can't walk him untill he's been sorted out.
