My dog's spay tattoo is spreading and looks blurry. Is it normal?

Hello! The peeling a week afterwards sounds like a normal part of the healing process for a tattoo. As long as it is not very red, swollen, or having any discharge, I would not worry about it being infected. I hope this is helpful! Thanks for using Petco Pet Education Center, formerly Petcoach!

Yes, bruising can be very normal as long as it is not severe or progressive. This amount of bruising is normal and usually caused by little vessels in the skin that bleed during surgery. I would monitor the area closely and the bruising should start to improve over the next few days. Contact your veterinarian if it is progressive or if your dog has any heat, swelling, or discharge from the incision.

Changes in skin color to a black pigment are often due to hyperpigmentation, which occurs secondary to chronic inflammation or irritation. The most common cause of this would be allergies (or atopy). Allergies usually show up between the ages of 2-4 years, so Pearl is right at that age. I recommend touching base with your vet to discuss if they think it's appropriate to start Pearl on an allergy treatment. Hope this helps! Here's a bit more information on allergy management if you're interested! https://www.petcoach.co/article/9-common-treatments-for-allergies-in-pets/

Hello, This green ink looks like the kind often used in a tattoo. Tattoos are commonly given to pets when they are spayed or neutered, so if that no one attempts to re-do the procedure. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach.

I recommend contacting the shelter vet to have this assessed - it may be simply a sensitivity reaction to the stitches/tattoo ink or could possibly be related to poor healing, a mild hernia or abscess in the wound.It is a good sign that she is otherwise well and although not an emergency situation the earlier this is assessed and corrected if necessary the better chance of a full resolution

It looks like there could be some inflammation at the site of the incision. That could be due to her body breaking down the sutures, or she caused some sort of trauma to the area. If she is acting normal and you don't feel any swelling around that area I would wait and see if it improves. But if there is swelling, drainage, or pain I would worry about a dehiscence (opening of the incision) which would be an emergency and she should see a vet immediately.

Thanks for using Petco Pet Education Center, formerly Petcoach! The incision looks like it is healing well so I would not be concerned about those dark spots. Those could be normal pigmentation changes. As long as the incision continues to look like it is healing, there is no need to recheck her. Good luck and best wishes!
