I like the house idea since the vet service will make "house calls." I do not care for the dots over the house. If at all possible to incorporate a paw print or animal shape it would be good - but maybe too much to build into the design with the house. I like the idea of having an image we could use without the text (most often the text would be with the image though) that would give clients an indication it's our company since the "M" and the house are combined together.
