Howdy all, I have a 12yo Golden Retriever named Bishop who has been licking his paw a lot over the last couple of days. Initially I could not find anything wrong with his paw but upon a very close inspection, I found a very strange yellow line on the inside of his left front paw (in between his toes). I initially thought he had a tooth pick stuck between his toes but the yellow line is attached to his paw. It almost feels like a piece of ligament that is on the outside of his skin, but his paw doesn’t look red or swollen like he had injured the ligament. His paw is very sensitive though. I have included a picture and am hoping that you guys might have a good idea about what this could be. I know that I should be taking him to the Vet first thing, but I lost my job due to the Coronavirus pandemic and am now facing eviction so I am not sure how I will be able to afford the vet bill, I am trying to schedule an appointment through my local rescue to get this poor guy taking care of, it tears me up inside seeing him suffer like this.
