You've not picked the easiest keyword! Over 13,000,000 results in Google! You're gonna have to do a lot of work to rank for that keyword.
I'd suggest you try an easier keyword. Or spend big money to improve your site, on page and off page.

Given that "labrador training" gets about 500 searches per month, getting 20 visitors a day isn't too bad.

Try to rank your website on different keywords to increase the visitors.

Try for low competition keywords with average 500-1000 search volume. It will be easy to rank

You should try building more backlinks, promote it on social media, forums, blogs, anywhere you can to get some more traffic.

If you post a reply and then get an error while posting (broken image) then your post is lost. That is what happened to me just now. I got the error page and when i hit back my post was gone. The forum should support auto saving. Sorry, too tired to write everything that i already wrote once again.

you need drive a good traffic to your website it is a good way and it can be Facebook, Twitter, G+....

Existence of every business is to generate revenue and for that what you need to do is let people know that you exist. that can be done in a lot of ways, but the easiest way is creating a referral market for your business. and believe me in the niche you are you must be looking for people around you and not from or around the country. so target locally and brand you self rather then waiting for rankings.

How it can be done?

Create a referral around you site but updating training videos , pics of dogs you train as people love fluffy Labs and for sure ina span of 15 to 25 day you will see a boost in traffic not rankings
