For the past couple of days my oldest boy has driven us a bit mad following our oldest girl, licking, chattering of teeth and trying to hump her, shes is not due in season until august/september, she not swollen at all so i kept saying she not due in i think the old boy is starting to lose his marbels, until last night when she started scooting her bum across the lving room floor, so my first though could her anal glands be a bit blocked, now could the fact she may be a bit blocked up be causing him to think she is coming in? She is going for a quick trip to the vets as well to make sure they are not blocked up due to a infection and the smell of that is fooling my boy, and any tips to stop it happening again (in over 15 years of owning dogs never had a dog scoot).
