LSI keywords for blog tags

Say I have a dog training wordpress blog, I insert key phrase "dog training" 5 times in my article and then add 5 blog tags (LSI key phrases,below)

Tags: dog obedience training,dog train,dog training,dog training collar,dogs training

As you can see there are too many key phrase "dog training" . Will Google devalue my site or page?

Thanks

If it was me, I would only use the main keyword once (dog training) and use anchor text for the others but making sure they link to a specific blog page, ie, if you have dog training collar, make sure it links to a blog post or page of that name.
