You are not alone my two all of a sudden seem in a state again. I bathed them Saturday and before that I got most matts out. Then yesterday we went on a 2 hour walk, it was a real mud fest but with lots of sand and swimming in rivers too. I showered them off when we came back and tonight I have been cuddling them and Bellas ears have set solid at the bottom and her armpits are so matted with small bits of twigs and sand. Jasmine does not usually matt but she is the same although not quite as bad, Its going to take me all week get them back to how they were and then I suppose it will be mud fest again next Sunday!!!
They seem to go from odd knot to total matted mess in 24 hours.
