Is 500mg Doxycycline 3x daily too high for my dog with lupus?
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.

Are doxycycline tablets with probiotics used for pet tick disease?
Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Yes, doxycycline is used to treat tick borne diseases. It seems as though the doxycycline is coated in a probiotic. I can't say I've seen this form in the US but it should be fine. Have a good day!

Vet Q & A
My dog has heartworm. Can he get doxycycline after his first shot?
I would recommend putting dozer on a 30 day course of antibiotics before the 2nd and 3rd injection. I would recommend consulting your vet for the medication and the proper dose. The antibiotic will kill the bacteria that live in the mircofilaria and are though to cause more inflammation.

Is my dog's 300mg doxycycline dosage for Lyme disease too high?
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.

My dog vomited Doxycycline for Anaplasma. What should I do now?
I would recommend trying the antibiotic one more time. Make sure Chloe has a full stomach prior to giving it. If she vomits again, I would recommend calling your veterinarian tomorrow and discussing what the next steps are. Thank you for using Petco Pet Education Center, formerly Petcoach.
