Okay tonight Tommy went to potty on his pad (yay) but he had some stuck to his hind end

so I cleaned him up with warm soapy water and it was all better. Except I remember something on here about the glands back there how do you know if they need to be squeezed or not and I don't really remember any of that thread, but it felt alittle different like it was a little puffy or something but it was not red.

I don't know someone please help. I don't even know if it means anything or not he is my first

Thank for any help
