What bacteria was found, exactly? This makes a difference in what antibiotics are best to use.Originally Posted by poolplayer33
My thoughts are your general understanding of antibiotics needs serious revision.
Cephalexin and and amoxicillin do have some crossover application, true, but they also differ greatly as well. Cephalexin has a much broader coverage of than amoxicillin, especially over staph infections, E. coli, P. mirabilis and Klebsiella sp. The only real advantage of amoxicillin is coverage over Enterococcus sp. Therefore, again, what antibiotics you should be using is dependent upon exactly what kind of "bacteria" you're talking about.
In this case, you're right. Amoxicillin is generally considered as good, in some cases better than cephalexin for the specific problem of UTIs.
However, TMZ is actually considered better than both of them for both UTIs and mastitis, as I mentioned in my first post. I only mentioned cephalexin because more people have it onhand than TMZ.
If you do not see an improvement w/in 3 days, you should discontinue amoxicillin and go with TMZ (or even Baytril/Orbax), because by now you will have run 3 different antibiotics in your pup, which kind of random drug use without actually knowing what bacteria you're dealing with is the recipe to cause a super-infection. So at this point, I would strongly recommend you get a specific answer as to what kind of "bacteria" you're actually dealing with here.
Good luck,
Jack
