I've noticed the past few days that gizmo is grooming this one spot every 10 seconds it seems. I'm half expecting to see a bald spot soon. He has a bacterial infection which is making his poos soft so I thought maybe he had gotten poo in his hair, but i have checked his body/hair a thousand times and I cannot see a thing wrong with it but he is constantly licking and tuggin at this one spot. Its right above his amputated arm/ under neck area. Any ideas why hes doing that?
