A bull frog might be pale because it is sick, getting old, or that's what color it should be.
The color green means the you are relaxed and laid-back. Green is also a color if you are sick. Green in the face means you are sick or going to throw-up.

Sick can be many colours such as green, red, yellow, etc depending on what you eat.
If your dog's nose is dry, they are probably sick. If the urine is a strange color, then that is a big sign that they are. I am no veterinarian by any stretch of the imagination, but your dog is sick. You should take them to the vet as soon as you can.
