If you haven't, you will.
Make your own homemade albon at 1/4 the price. Buy a gallon of Di-Methox (12.5% Sulfadimethoxine) from Jeffers for about 36.00, buy a gallon of Dyne for about 40.00. Mix 5 oz of Dyne with 4oz Di-Methox. Bam! You have 5% Albon. And you have enough to make almost 2 gallons for 80 bucks, versus 60-70 for a pint of Albon from your vet.
