Hi Linda,
Congratulations, Zia from me and my Labs - Savannah, Annie, Shane, Autumn and Chance. You two are an awesome team. It was so much fun watching you at Champs through the years.
My dog, Chance, has laryngeal paralysis, too. He had tie back surgery last May. (I'd only had him for 7 months at that time. He's probably 10-11 years old). The 6 week recovery period was labor intensive, and I still make and hand feed him meatball sized food every day. But he has gained a whole new lease on life and is able to breath normally again. The only restriction - he can't be in water deeper than his feet.
I don't know what Zia's situation is, but you may want to look into the surgery as an alternative course of action - especially as the weather gets hotter.
Again, congratulations and happy retirement to you both.
Joan
