My dog ate a crushed doxycycline capsule. Is it dangerous for her?

Doxycycline should be taken whole or immediately before food to ensure it is swallowed into the stomach, it should then be followed by a drink to ensure it is washed down. It can cause painful ulcers in the upper GI tract if it lodges here and is not taken directly to the stomach

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Boss will be fine, there is no need to take him to the vet. Doxycycline is used in dogs fairly often. At the dose he ingested there should not be any side effects at all.

I’m assuming both dogs are about the same weight. If so the doxycycline could cause vomiting or upset stomach but there would be no other major concerns. If one of your dogs is smaller you should repost your question. Be sure to let your vet know and to get a refill so the prescription can be finished.

Yes in two hours the tablet should have been absorbed and dissolved already. This medication must be given with food and water as well as can cause oesophageal inflammation. I would suggest to wait until next dosage and I would suggest to withhold food for the next 8 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, more vomiting, lethargy or inappetence. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

A part from possible oesophageal inflammation, Prince should not experience any other side effect a part from nausea, vomiting, and possibly diarrhea. I would not be extremely worried and just monitor him at this stage. Should you notice any signs listed above, a check up would be needed.

The extra dose probably caused the vomiting. Doxycycline does cause vomiting as a side effect. If the vomiting resolves, then I would not be concerned. If the vomiting persists, contact your veterinarian.

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!
