Itchy Bumhole

[AlleyG]

For a week or so now my dog's been scooting.

I wormed her and took her to the vets yesterday to get her anal glands drained.

Her anal glands were fine and didn't actually need draining.

The vet didn't seem very concerned but I don't want the dog being bothered by an itchy bum.

What else could it be? What can I do?

I can't see anything wrong around her back end.

Her poo is completely normal.

Vet said her vulva was fine.

She's four years old.

She's a mongrel- looks like a bit of every type of terrier around.

What's her poo like

Mine does this if poo is either runny or to hard
Also maybe need to get hair trimmed round it
