new and need advice-Hydroseeding

Hi there

Got a dog and then put the fence up. Was not really attentive to how little grass I had in that area. Rain has come and the dog is a muddy mess all the time. Askeda couple of friends and got the recommendation of hydro-seeding. Sprayed on, seed, fertilizer and straw all at once. Grass supposedly up in 10-14 days. Love to hear some opinions
