He is teething. He's just over 4 months old. What I've Been doing so far is giving him his rope toy that's been socked in water then put in the freezer over night. That's works well bit has a short life span. I have give him raw hide and they are ok but he loses interest very quick. As u may know a 4 month jrt has the atenttion span of a Nat lol.he's walked everyday and taken two massive walking over our feilds and woods on the weekend. He chews me and the misses, furniture, wires, mugs, my bedding,
