Cathy Hall Maxton, NC 1/30/2015 6:51:57 AM my 10 y/o chi has been on medications for CHF for close to a year, before this condition, he suffered from liver problemns and was on med.'s for 2 years before blood test came back within normal range. He is beginging to have coughing and chokeing spells, and has at times weakness walking. I am taking him monday for a check up, but wonder when do you know it's time to let them go? I want him with us forever, knowing that's not an option, how does one decide? He is taking meds for his CHF, but had to stop his allergy shots, using otc bendryl which is not effective. I love my buddy, what is best for him?
