Browning Dog Training & Behavior Supplies

My 3 year, 7 lb, blonde mixed terrier that I adopted the end of December with a pinkish white belly has recently had a browning of this area. She acts fine, no scratching. She has a light/pinkish nose. Does this require vet attention?

Good morning. I had a question. I recently just got a Maltipoo puppy and she is 10 weeks old. I have never had a dog before so I really don’t know how to potty train her. She does her business anywhere in the house and she occasionally pees on the pads. I wanted to know how can I fix this? I had another question. I noticed that she had a red spot under her eye where the browning is the other day and it eventually went away. What could’ve caused this? Her right paw is red as well.

My normally white chihuahuas testicular have started turning brown on the inside of the ball area. Also his punishment has turned a darker color. He is 6 months. I'm not sure if this is pigmentation or something else that is serious. He has started getting brown pigmentation all over his legs and stomach area as well.
