It looks like Ddog may have conjunctivitis. He's woken up with a red, bloodshot eye and a thick green crust. I've cleaned the eye but what do I do? Is this a vet job? Also, is it contagious? He goes to a dog walker during the week, so will obv be around other dogs.
I've owned dogs for a while but this is a new one on me, so any advice would be great, thank you. :)
