thank you jerry and michelle for the information. mickey is miniature schnauzer. he just turned 9. i was in shock to find out he has OSA. as i understand it only about 10% of small dogs get OSA. mickey comes from champion bloodlines. i purchased mickey when he was 10 weeks old. i could not have asked for a better dog. he has been the love of my life. before getting cancer he had no other health problems expect for bladderstones which he had surgery and hydropropulsion for. he recently had a stomach ultrasound and chest xrays and nothing abnormal was found. he is not overweight but the oncologist told me she didn't want him to gain anymore weight. i have cut back a little on his royal canin urinary so dog food (moderate calorie). mickey had cancer about 2 months before he was diagnosed. he was limping and i was taking his sweater off as i raised his front leg he cried out in pain. i took him to the emergency vet the next day. the xray they took showed an osteolytic lesion in his left humerus. and there was a moth eaten appearance on some of his bone. the bone had become soft so they could not biopsy it. mickey has had pet insurance since 2010. it is called Trupanion. they have paid 90% on everything cancer related after i met my deductible of $250.00 the only other thing they don't cover is the consultation/office visit charge. without insurance i likely would have had to put him down.
