Had ddog for 7 weeks now and we're absolutely smitten with him. He's a cocker spaniel and one thing I've noticed about him is that in the last few weeks he's been getting intermittently red eyes and what looks like an extra lower eyelid or something on one eye. Really difficult to explain so have attached a pic. It doesn't seem to bother him in any way so not sure if a vets visit is warranted although totally happy to do so if needs be. Any ideas?
