Black Golden Doodle losing hair in spots

[Ron Dupuy]

We adopted a black golden doodle, who has become one of our family very fast... however he was so matted we need to have him shaved down so he could regrow out. I noticed about 4 weeks ago his hair was not growing back in spots. My groomer said this is probably a thyroid problem, He eats fine, acts fine, and doesn't show any sign of irritation.

Any advice out there would help
