A rather disgusting smell.

Hector is on my lap i then smell something revolting sort of like pee smell mixed with must. look at my leg and there is a wet patch about the sie of a 5p'

I look at the underside of Hec and his willy is dry lol so the only other orifice it could have come from is his bum.

Does anyone know what it is? it smells bloody awful.

Sounds like he vented his anal glands!

URG PUKE! Why did he do that?

Excitement, nerves who knows lol!
Becky

So every so often they just let this gross smelling stuff out of their glands?

It should be expelled when the dog goes to the loo. One reason why you need to make sure they are firm otherwise the anal glands aren't expressed properly and can cause problems.
Becky

Ah ok thank you.
We were in the shop and he hadnt poo'd for about 4 odd hours so maybe that was why.

Probably feeling a bit of pressure!
