When I saw this dog in the show, my first thought was “Is this a dragon through the portal? Or just a regular dog?” The fact that the dog was purple (and the name) made me think she was probably a dragon, but the black single colour eyes made me think dog, as they’re a common design choice for non-sentient animals in the series (And babies, I guess.). But then again, I don’t think any dogs in the pony world are bright colours. Hell if I know.  
I considered giving her the black dot eyes she has as a dog, but it made her look weird. I went with the blue from her bandana. She wound up looking vaguely like a g3 design, what with the purple-pink colour and the pastel-y colours. I kind of like it.  
Any feedback would be great.
