I like the clean, professional, uncluttered look! Well-done.
I am not sure how much time you want to put into it, but one thing that would be a nice touch would be to have the main picture (with the dog and the Pets n Vets logo and text rotate with other animals...keep the text and everything else the same, but just swap the dog for, say, a cat, and a bird, and whatever else they handle.
