thank you for your thoughful comment Seeana...will do.
Hi if I were you I would have her checked out as she is getting on a bit.... the Vet will know if it is anything to worry about.Could be a few things but when anything out of the ordinary shows up only a professional can really put your mind at ease.
Please let us know the outcome as its not what is on show its what is behind it and hopefully there is nothing for you too worry about.
