Browning Dog Coats & Jackets

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.

Crusty brown nosrrils

where my dog has brown fur she is losing it but not on the white fur

My dog's teeth are brown at the top (not his gums)

brown have flu all time of the year how to help him he is very old

What is going on with the dark color in Peppers touge

hard red bump that is scabbing over

What could cause a new brown area on the bridge of cat's nose?

My fawn and white IG's skin on his testicles, inner thigh and legs, and a bit in front of his ears normally light, darkens heavenly, then lightens again in fall. He is two years old and this is the second year of this occurring. No other symptoms. Is this normal?
