hi yesterday my dog was down the garden and he lost the strength in his back legs and slowly collapsed he had really pale gums and he was slavering alot and then he weed were he was laid but this isn't the first time it happened about 3-4 weeks ago and we took him to the vets and they took his bloods and his white cell count was up he was tender around his stomach and ribs and her had a temperature, they treated him with 5 days of anti-biotic injections and discharged him but now i'm worried it's something more serious.Please can you give me some clue to what it could be he is a male boxer and 8 years old
