I won't harm to give a little Tylan. You can get it at any feed store, and even though it's not specifically labeled for dogs, it has some significant useful benefit to dogs, specifically for bronchial/pneumonia-like problems. The reason this drug is generally contraindicated for dogs is it tends to cause soreness and possible infection at the injection site, but being aware of this and disinfecting the injection site are ways around this problem.

Tylan comes in the following sizes: Tylan-50, Tylan-100, and Tylan-200, which simply indicate increased concentrations of the drug (50mg/ml, 100 mg/ml, and 200 mg/ml, respectively).

Since this drug is dosed at 4.45mg/lb, IM, SID-BID (every 12-24 hrs), and since there can be problems associated with pain or reactions to the injection, it only makes sense to buy the Tylan-200 to minimize the amount of fluid that enters the dog. To show the difference in amounts to be injected, a 40-lb dog would need 3.6 ml of the Tylan-50, which would burn like hell, but yet he would only need 0.9 ml of the Tylan 200 which limited amount would help minimize any pain or lump from forming.

If 0.9 ml of Tylan 200 would be the dose for a 40 lb dog, then you'd only need about 0.25 ml (¼ ml) for a 10 lb pup--or half of that for a 5 lb pup.

Adjust the actual dosage based on the size of your individual pup and give for no more than 5 days.

Hope this helps,
