I noticed this evening that Yoshi has a growth on his back below his right shoulder? It is mushy feeling and about the size of the tip of my thumb to the first knuckle, it moves around with ease and feels like it is under the skin but not attached to the body underneath it? He is acting fine and it doesnt appear to hurt him when I am feeling it. It was not there earlier today, I know because I give him what I call puppy massages and always have my fingers around his shoulders. Does anyone know what this could be or have experienced this. It is 10 pm my time and I cant call the vet until 8:30 am and I will probably lose sleep over this
I wanted to add that he hasnt had any vaccinations lately.
