Hi there!
For me web design is about evolution, so my advice would be to make small changes to bring the site up-to-date. A few things I'd do:
-> the blog link currently doesn't seem to link to a blog (there's an entry what a blog is but nothing else). Unless the blog is to launch soon, I'd remove the link.
-> remove the scrolling ticker text - it's not used much these days outside of stockbrokers and can make a site look dated. I'd incorporate the text into the page content.
-> internet is global, so I'd include something on your homepage / header that tells visitors where you are in the world [your grooming services are fab, but not if the dog is in Germany

]
-> forums can be great ways to attract business (just look at this one!) so why make it visible to registered users only?
All the best! Edith
