This year has been very hot and dry and my WP show gelding started coughing badly and has had difficulty breathing. I spent a lot of money on steroid meds from the vet which did help but only temporarily. I want to thank Angela Clarke for bringing her Equi-Resp machine to the barn and treating my horse. After a few silver treatments my horse started coughing out his congestion which wasn’t happening with just the oral meds. It’s been 3 weeks and 8 treatments and my horse is no longer coughing or having trouble breathing. I am a strong believer of this product and have purchased my own to continue treating my horse to keep him healthy.
