well thanks for all your reply's I will keep a close eye on it, it feels pretty soft to touch it just looks big to me Ill get the vet to have another look at it when shes due for her 12 week vaccination , doesnt seem to worry her I think Im just being a worry wart , My old dog had one she lived to 15 yrs of age so Im gonna just try to forget about till I speak to the vet ... thanks again
