I've checked the Alabama Rot reported cases and there have been none logged in the EX postcode since 2021. This does not mean that it can't suddenly happen anytime, anywhere, but going by my friend's tragic experience, the symptoms don't sound the same in your dogs sazzl. I've just found her message at the time.
Polly then developed a limp. ......Her front paw soon ballooned to twice the size and eventually started oozing blood. Two days later Polly had stopped eating for a couple of days and was lethargic. She is obsessive about food so this should have been a sign. She was transferred to the vet hospital where she stayed over night. She did not respond to antibiotics. She was due to go to a hospital in Bristol for state of the art imaging and an operation to remove the obstruction last Monday. By this time the vet had begun further tests and diagnosed kidney problems and realised that she was a victim of Alabama foot rot. ....She was put to sleep last Saturday. Horrible horrible end. The information about this appalling condition is frustratingly vague. The incubation period can be a few hours to 14 days. We shall never be sure of the source of the infection. It seems about fifteen times as many dogs are killed through road accidents which highlights how rare it is. It is some kind of bacteria associated with more woody areas and an autumn and winter issue apparently. But it is all vague hearsay and because it is rare, little specific research has been undertaken and very little definitive knowledge exists.
If you are worried, sazzl, keep returning to your vet.
