When given though, it should be a single, not in a combo. 
 Sentinel is just Interceptor with Program. It is a good drug. The Program (for fleas) just makes it so they can't reproduce though. It doesn't kill them.

  Thank you. The vet told my dh that lepto is very common in our area. I didn't research it, b/c I just assumed that the cons outweighed the pros. Guess I better research it a bit more.  She also said the we could catch it also.  
Sentinel sounds ok. I'm just so leary of any drugs going into my baby. 

  But since she's outside alot & we live in the good 'ol south which is horrible for fleas, she will need something. Oh, decisions...
