like with anything you read on a forum, do your research and know how to use meds and be very careful not to overdose your dogs.
With that said here are some must haves for dogs owners and a great way to avoid large vets bills. All of these require no prescription from the vet.
If your dog has diarrhea for a few days Metronidazole is a great antibiotic that works wonders on the gut. I always use it at the first sign of diarrhea and it stops it about 95% of the time.
11.5 to 15 Mg per lbs of body weight. This is given BID (mean 2x a day)
your dog weights 40lbs so take 40 x 15 = 600 mg or you could use a smaller dose 40 x 11.5 = 460
so since it comes in
250 mg and 500 mg tablets I would give 500 mg 2 times a day for 7 days.
If you have smaller dogs then like puppies order 250 mg tablets
If you have dogs over 40lbs order the 500 mg tablets

you can overdose puppies and small dogs easily with metronidazole and have neurological problems. So I would always use the 11.5 x the body weight dosage and not ever give it to pups under 10lbs but that is JMO.
WARNING: Use any drug with caution and realize that a small percentage of dogs can be allergic to any one of the following antibiotics. Do NOT give antibiotics to a very young dog without consulting a veterinarian, as some drugs (like tetracycline) can harm puppy teeth.
Chephalexin is a great antibiotic for anything else that is not GI related. I use it for any cuts or anything that requires antibiotics. There are exceptions where more powerful antibiotics are required but if you needed those you would have been to the vet anyway.
Cephalexin only comes in oral form, and the dose is 15 mg per pound of body weight, given every 8 to 12 hours depending on the severity of the problem. If you are using a maintenance dose, give it every 12 hours. If the dog has an infection already, use it every 8 hrs.
