Poor Betty

Was the Vets last night . On her last walk something happened . Her mouth all swelled up so Rachael took her to the emergency vet in Woking , Betty was given an injection etc . We were hoping she had not eaten a mushroom as they can be fatal . The vet said bring her straight back if she got worse .
Anyway she was fine today and the swelling has gone down . We thought then it might have been a Wasp .
