Congrats on your boy, Austin. Have you heard of a product called "Showstopper". It is supposed to be fantastic for coats.
Good luck. Keep us posted.
First to the OP:: Welcome to DT!!!!
I've used Showstopper for about 3 weeks and it has improved my red boy's coat by 40-50%. He had a thin coat, not much luster, shedding due to the last Kibble we fed.
Now he has a full and soft coat, less dandruff, and looks awesome. Though, I'm not sure if you can give it to puppies. Here is their website if you want more info:::Showstopper Website
