I have a Bernese mountain dog and heās nearly 4. The last few weeks we have had issues with him biting his back end. Heās been treated with numerous things which have helped but the dry skin and scabs are still present. The last week or so he has been very sensitive in the spine area, to the point of when itās touched he loses control in his back end. The vet has done bloods which were normal, given him pain relief and I give him antihistamine. Heās also been referred for an MRI as heās doing something called fly snapping which Iāve read can be a sign of seizures? I would like to know if anyone has had similar issues with this in their dogs? Iām so worried as google is great and bad at the same time! He also does phantom scratching now and again, and when heās resting. Thanks for reading
