I checked out your blog and I like the "journal" design for your blog posts. What bothers me is I can't make out your background design.
A good pet blog. But its not match with the domain name. There are cat in the blog. You need to concentrate only on one pet such as dog.
Nice design and layout. Do you also have plans of monitizing your blog ? It looks so clean and fresh.
I have seen this design in 2 or 3 other blogs as well. I would say that you need to beef up your blog with quality posts. try including some authoritative how to guides. First of all realize why you started the blog. then build on your aspiration and get quality leads
Your site has great background, keep it up. You can also add humorous dog video in your site to make your blog more interesting. Keep creating blogs for other animals also. Great job done by you.
