Every now and then (2-3 times a year) my dog gets twitchy and bites at herself, always on her left side, until there is a visible bald patch. It comes on very quickly (left the house this morning and she was fine, came home to clumps of fur everywhere and a semi bald dog). She also seems to get very restless, pants a hell of a lot and just seems unhappy.
Have taken her to the vets every time, spent a hideous amount of money and they have come to no conclusions :( obviously, will be taking her to the vets yet again but feel I will be wasting my time, as it always last 3 or 4 days, then she's back to her normal self and it clears up.
Her diet hasn't changed at all; she's fed on Applaws dry food, dentastick every day plus raw bones a couple of times a week. She has some scraps, but only potatoes, plain pasta/rice, meat etc, never any sauces or anything as she's very quick to get a runny tummy!
I'm just at a loss as to what it could be. Any ideas?
