I have had asthma in and off for years. However, I usually only use my breathing machine and inhaler when seasons change.. 1-2 times a year. Have to use them 2x a DAY FOR A MONTH NOW. The only thing different is I had to have my dog almost completely shaved due to knots a month ago. My first sign it may be the dog.. gave him a bath, had full blown asthma attack closed up in shower w him. Had anyone else had any breathing issues with dander shedding so much worse without his hair?
