My dog takes doxycycline. Is splitting the dose still effective?

Hello. I wonder if perhaps the labels were mixed up. Normally, Doxycycline would be prescribed at 5-10 mg/kg ( 136-272 mg ) every 12 - 24 hours & the niacinamide 500 mg every 8 hours. Now if your vet actually sent home tetracycline, then the dose would be 500 mg every 8 hours. But if the Doxycycline was substituted for the Tetracycline, then the total dose should be less. I would definitely double check this with your veterinarian as soon as possible. Thanks for using Petco Pet Education Center, formerly Petcoach.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! The maximum dose of doxycycline is 10mg/kg twice daily (or 20mg/kg/day). If you gave Chylo around 33-35mg that is 20mg/kg and he should be fine. Do not give him any more for 24 hours. Doxycycline is very hard on the stomach so he may have vomiting. I hope this helps and have a great day!

If you mean you have only been giving it once daily instead of twice daily then go ahead and give your pm dose tonight and tomorrow start your twice a day dosing as per the label (1 with breakfast and 1 with dinner). Just make sure you give with food as doxycycline can cause tummy upset. It is okay you have only missed a few days and will get back on track tomorrow. When your vet is open again just call to let them know so they can note it in his medical record. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. The recommended dose of doxycycline for Lyme disease is 20mg/lb once daily, so Joey should be taking around 200mg a day. Rarely doxycycline is used at higher doses or more frequently than once every 24hrs. Please, get in touch with your local vet to discuss the treatment as it sounds that the dose should be slightly adjusted.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Kira. This is a great question! It's absolutely fine to give her the full dosage at the regularly scheduled time. Doing that will cause no problems. I hope this helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! You can just continue it as prescribed if she is tolerating it well. There would not be any need to skip it for a certain amount of time before continuing. She is adorable! Good luck and have a great day!

Hello and thank you for your post! With Ehrlichiosis I typically dose at 5mg/kg every 12 hours, which equates to roughly 200mg twice daily. The 100mg dose does seem a bit low. I typically treat for about 6 weeks as well. Based on cases your vet has seen, he / she may have a reason for dosing at the 100mg twice daily. That is what I treat Ehrlichiosis with though and is effective. If you have any other questions please feel free to contact me. I am also available via consultation.
