I went to Tractor Supply Store and bought the Tylan 50 (50 is the small bottle, wish I would have gotten the larger one) needle and syringe and started oral treatment. 2 tsp (I will get back with you for the ml amount) per 1 gallon of water mixed with a little sugar to take the bitterness out and changed daily.

It has been a little over a week since I started treating and most if not all the sneezing has gone away. I will continue treatment for the next 3 weeks as recommended.

I listened to their lungs and did not hear a rattle in their lungs and I also believe I caught it and started treatment soon enough. I do not believe someone will have the same luck with rats that are not treated quickly or are seriously ill, or it may take more time and a different medication to fix.


Just a little more information to what you can expect with the liquid Tylan.
I've used both water bottle and oral treatment. The oral treatment is highly effective (so Ive found) but it is harsher. I would cut your treatment short by a week if you are actively breeding. Tylan does affect fetal development. Rats treated for two weeks or longer seem to loose fetal weight and drop a smaller number of pinks. Some are effected more so than others by Tylan. I had one female drop 15 with no issues and another who lost fetal weight and dropped 4.
