This senior duo may appear to be a fairly normal pair of dogs, but when you take a closer look, it is hard not to see a strange mark in the middle of their heads.

@allthefosterpups This is the story of my foster dogs Peanut Butter & Jelly. Their story is a sad one, but hopefully one that will soon have a happy ending once they find their forever home. PB & J are just the best of friends who have had a bit of a rough life so far. But they’ve shown us once again how resilient senior dogs are and how much love senior dogs have to give, no matter what they’ve been through. Peanut Butter & Jelly are a bonded pair available for adoption together from Muttville Senior Dog Rescue in San Francisco. Peanut Butter is 12 years young and he weighs 22 lbs, Jelly is 12 years young and weighs 13 lbs. #chihuahuastiktok #seniordogsoftiktok #rescuedogsoftiktok #adoptdontshop #fosterdog #fosteringsaveslives #chihuahuafanclub #muttvillesf #bondedpair ♬ original sound – lisa and senior mutts

Their foster carer Lisa, told Newsweek: “Their previous owner had glued some sort of jewels to their heads. The jewels had to be removed by the vet at the shelter and the glue that was used caused burns to the dogs’ skin.

“Both dogs now have these permanent scars on the tops of their heads from where the jewels were glued on.”

Peanut Butter, is a larger brown dog whose scar is more prominent and Jelly, a chihuahua mix, is black and therefore her scar isn’t as obvious. The jewels were removed months ago and their hair still hasn’t grown back, so they are likely to be permanent scars, said Lisa.

Lisa, who lives in Concord, California, recently shared a close-up video of their heads on TikTok. She describes them as “special little scars which make them even more unique.”
