Had a prescription for gabapentin come across the bench the other day for an 8 year old, and boy the dose seemed high. As I prepared to contact the prescriber, I realized the patient had four legs and a tail.

For the life of me, I couldn't find a decent vet dosing guide. Do you have a go-to?

I recently got a phone in script from a vet for a boxer. Levothyroxine, 700 mcg bid. I questioned this VERY adamantly. I don't have much clinical knowledge about dogs.

2nd Plumbs; I think it costs around $70-80 or so. All weight based and species specific (sometimes breed specific) but does come in handy.

I don't think an exotic animal reference is worth it; mostly dogs, cats, mouses/hampsters, rabbits, etc. in retail.

If all else fails, dosing estimate based on weight--obviously, not all human drugs are safe for all species, and species may metabolize drugs differently than humans....but with the commonly prescribe drugs by vets that are going to be seen in retail (usually only control's & benadryl that the vet doesn't want to carry in his office), dosing by weight will give you a starting idea.
