      Yes! They are carnivores and dogs and sea lios are closer to each other than either is to, say, cats. Have a look at this evolutionary tree: http://www.whozoo.org/mammals/Carnivores/carnivorephylogeny.htm.

      My research is very related to your question; becasue sea lions are related to dogs they can catch some of the same diseases, which is bad news for the sea lions that live on the Galapagos. They have been living on the galapagos islands without humans or dogs for a few million years, so their immunity is not very good (because they haven’t been exposed to many diseases). However, now more and more humans are taking their dogs out to the Galapagos, the sea lions are in danger of catching diseases from the dogs.
