I have a JRT adult bitch. Over the last 12 months the skin on her legs has become more pink so that you can see it through the white fur. She is short haired. Recently the skin on her belly has become pinker. She isn't itchy, and is bright and lively and in good health. Her coat quality is good, even over the "pink" bits. My other JRT is unaffected. I suspect an allergy, I have bathed her, changed her bedding and changed her food, but to no avail. Any ideas? Thanks in advance.
