Well, I have an interesting solution to this.
I went to the vet and got a solution for sensitive dogs, to clean her ears. There was nothing came out of her ears, and she kept scratching, so I figured I should take her to the vet.
She went to the vet on Friday evening, he said they looked slightly red, but nothing that would make him think there was a problem, no sign of infection etc.
Gave her a steroid and antibiotic shot for the itching and suggesting keeping the hair on her head short as the heat etc may be irritating.
She was booked for the groomers on Saturday anyway, so I said to the groomer about the itching, and she plucked her ears, and trimmed around them but said there was no need to cut the face short. She asked if I had had her anal glands done recently. I havent, and Maisie is just after a bad bout of diarhhoea, and hasnt been herself since.
Anyway, the groomer said that sometimes when anal glands are full, it can cause dogs to itch towards the front of their bodies. Maisie wasnt scooting her bum, or itching the back end at all, but her anal glands were very very full when the groomer checked them.
Well, today we have a different dog!
She is full of life again. She is still scratching a bit, but its more normal now, and not the hard scratching she was doing on her ears. Poor thing must have been so uncomfortable before.
The groomer fixed what the vet missed!
