Do I need to see a vet?

It's been raining all day. Every time I've been on my walks I've got soaked through to my skin so I've had to be dried thoroughly when I get home. While Ann was drying me just look what she found on my ear............................. a little cyst type lump. What do you think it is and where do you think it has come from?



It's not bothering me. In fact I didn't even know I had it until Ann told me. But do you think I need to see a vet. Ann has 'googled' it but hasn't really come up with any ideas???? I guess the main problem will be if it bursts and then becomes infected because then I might need antibiotics.



I guess we'll just keep an eye on it and if it gets any worse we'll go and see the vet.
