Hi I have a Gizmo also and he did the same thing at that age,when he'd start bitting me I'd tell him no bites I want kisses, give me kisses and sure enough the little stinker would kiss instead of bitting. When I noticed his teeth would really bother him I would give him a frozen face cloth( wet a face cloth twist it and put it in the freezer) and he just loved those. Good luck xo |
