Why is my dog's skin turning gray again after car accident trauma?

There will be areas around the wound where the skin will die off, then new skin cells will move in. The grey is likely dying skin whilst the red is the new healthy skin. If the wound looks particularly red, or is smelly or pussy it would be necessary to visit the vet as antibiotics will be needed.

Some color changes to the skin can be normal with aging. However if the spots appear red, itchy or bothersome to Olive, grow rapidly in size, or develop a wound/sore, then having it checked out by a vet to rule out other issues such as allergies, infection or illness is always best.

This do tend to grey as they age and is definitely something I wouldn't worry about. Keep in mind that a dog is considered a senior around seven years of age. However, this does appear more leukotrichia, which is a disorder where the hair turns white. It's not harmful, but could continue to progress and cause Alfie to have a whiter face. If you are happening to notice any problems with his skin, then it would be best to have a vet examine him, because the hair can change color with damage to the skin. I hope that helps and all is well with Alfie.

Skin darkening can occur due to natural aging, low level irritation from infection or allergies, a healed wound or changes in hormone levels from hypothyroidism. Your veterinarian may be able to determine the exact cause after a thorough physical exam. I hope this helps and please feel free to post any additional questions.

Some dogs will experience graying at an early age. This is common on the face and muzzle but can be seen on the legs and abdomen as well. If this is been an abrupt change or if it is accompanied by any changes in the skin such as crusting or redness, I would recommend an examination with your veterinarian as it could indicate an infection, mange or autoimmune issue. If it is just white or gray hair that is occurring gradually over time, it is likely just a genetic predisposition particular to your dog.

Or Sometimes loss of hair or a deep scrape seems to change the quality or pigment of the skin or hair (I don't know if there is a good medical explanation for that). Of course, there are also infections, auto-immune diseases, and other reasons skin color can change. If the skin is completely normal other than being a lighter shade, it's been going on for longer than a month without change, and Sissy doesn't seem bothered by it, its PROBABLY nothing to worry about. If it has come up suddenly or spread quickly, changed alot in any other way, there are other spots where it starts to happen, or Sissy seems at all bothered by it, it's time to seek a second opinion or pursue testing (skin scrape/impression or skin biopsy are reasonable next steps). Hope this helps and best of luck to you and Sissy!

Thanks for using Petco Pet Education Center, formerly Petcoach! The answer is probably not. If he is grey/silver this is especially common. If you are seeing other signs like scabs, pimple-like rash, increased drinking and urinating, or increased appetite, see your vet as these could be a sign of other conditions. Best of luck to you and Winston!
