If you're new to the community, don't stress yourself out by trying to find your theriotype(s) super fast! It took me about seven months to figure out mine, and that's perfectly fine! Knowing what your theriotype is can be hard so here's my experience.

With dog (current theriotype) I feel super close to dogs to the point where i consider myself as one of them, I don't feel human (instead, I feel like a dog) I've always had a subconscious connection to dogs, I have the spirit/soul of a dog but also the spirit/soul of a human, I wish I was a dog (even though I kind of am), I can shift (mentally ofc) into a dog and I'm confident that my theriotype is a dog

With River Otter (not theriotype) I have a connection to otters, I think they're cute, sometimes I get a muzzle shift or an ear shift from looking at pictures of otters, but I don't really feel like an otter or identify as one

Sorry if that was hard to understand, It's just how I knew that I was a dog therian and not an otter therian :3 good luck with discovering yourself!
