The average dosage of SMZ-TMP for dogs is about 13mg per pound given once daily. For a 50 pound dog this would be about 650mg daily. However, if you need to give a medication such as SMZ to your dog it is best to contact your local veterinarian for the correct dosage and usage information as this dosage can vary depending on your dog's personal needs or illness. Antibiotics should only be given under direct veterinary supervision as the antibiotics you have on hand may not be the correct dosage or even type for your dog's current condition. Giving a medication in the wrong dosage or frequency may make the illness worse or cause side effects that are detrimental to your dog.

Hello. There is a dose range for SMZ-TMP depending on what the drug is being used to treat. An average dose for an 80-pound dog would be 545 mg every 12 hours, but doses of up to 1636 mg are routinely used in some more serious conditions. So your dose may be appropriate for your pet, especially if she is responding to the medication. Thanks for using Boop by Petco.

The usual dose used is 15mg/kg but you could go as high as 30mg/kg; so a 26# dog would need between 177mg to 354mg twice a day. I do think the dose is high so please call your vet and ask. Personally I would use 1/2 of a 480mg tablet twice a day. The person who filled the prescription may have made an error. The drug is very safe so I would not be worried about it's safety. Remember, any drug can cause side effects but I use this drug A LOT and very rarely see any side effects and if I do, they are usually mild.

I'm so sorry to hear that Kennedy is not feeling well. There are a number of potential side effects to SMZ TMP and they can often occur after being on the antibiotics for a period of weeks. I am attaching more information about that below. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=617 So, I would recommend contacting your veterinarian and see what they would recommend for Kennedy at this point. They may want to do a recheck exam on Kennedy or maybe even change her antibiotics. Good luck! I hope that was helpful and that Kennedy feels better soon. Thanks for using Boop by Petco.
