Looking to get a tattoo to commemorate my dog

My dog recently passed and I want to get a tattoo to remember her but I'm not sure what to get, she saw an albino squirrel on our last walk through the park. At first I was thinking her ears or paw but would a squirrel tattoo be weird? And is there a good way to do an albino squirrel?

Edit: I'm 30M if that matters
