My dog has a resistant infection. Is his Baytril dose correct?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 48.5 lbs

My dog has antibiotic resistant Pseudomonas on a toe. 2 weeks Synulox and 2 weeks Baytril did nothing. Toe amputation was done. Wound broke down and rest of toe needed to be amputated. Post op I was told to give Baytril 50mg, 1.5 tablets (75mg) ONCE a day. Dog is 22kg. I was given 21 tablets (enough for 1week at 2x a day or 2 week at 1x a day). I think I should have given the Baytril 2x a day. Am I right?

Hello. The range of doses for treating Pseudomonas is quite large, but we do recommend treating at the higher end. In some cases, this would mean your dog may need up to 400 mg per day ( 20 mg/kg/day ). At the very least, I would probably recommend the 75 mg every 12 hours or 150 mg once a day. Please check with your vet to make sure the right directions were given to you. Thanks for using Petco Pet Education Center, formerly Petcoach.
