Hi Magicabdab, grass is starting to grow now and what you could start off my doing is applying a weed and feed mix and in about 2 weeks give it a right good scarify to lift any dead grass / moss up.
I would then suggest to aerate it and apply a top dressing with a mixture of hardy rye grass (as you've got dogs). This is what I do every spring and get really good results.
There are some fantastic guides in YouTube that you can use for reference should you get stuck
