Ok, this will sound off the wall, but bear with me.
I work for a veterinarian, with animals that have shedding/hair issues, we advise more Omega's. And give it time.
That said, eat Tuna! Low cal, high protein and Omega's. It does work. One can of tuna in water daily, and give it at least 90 days!
It does work!
The other thing we advise is a bit, maybe a teaspoon of bacon fat once a week. Given, dogs are much smaller than us, so the 1 teaspoon, but, we still need a bit of bad fat for our bodies to function well.
So, eat some tuna each day, or salmon is good too, and one slice of bacon weekly.
