Why is my dog so lethargic after taking Clavamox for bronchitis?

Her eating grass and feeling unwell could very well be the clavamox, it is known to cause nausea. try giving the clavamox about 10-15 minutes after a large meal. it can reduce this side effect. the sleepiness could be both the antibiotics and the kennel cough, it's quite normal but she should start feeling better soon.

Hi, The dose of amoxicilin/clavulanic acid is 12.5mg/kg -25mg/kg so, your dog was prescribed the right dose. It would be very unlikely that Guiness was subdued because of this antibiotic, as lethargy is an uncommon side effect of this medication. However, in rare cases this type of adverse reactions are possible and if you notice that your dog is lethargic after the next dose of antibiotic you should get in touch with your veterinarian to possibly change the type of medication he is on.

I hate to hear that Scout has an anal gland infection. I would recommend to call his veterinarian and discuss the lethargy. The lethargy could be a reaction but could also be due to the abscess. I would not advise to stop the medication without talking to Scout's doctor. Make sure you are giving the medication with food. I hope he starts feeling better!

If the clavamox didn't resolve the issue, I would bring him back in for additional exams such as neurologic examination, bloodwork, x-rays, etc to try and narrow down the cause. These can help rule out metabolic or infectious issues, injuries or joint problems, or neurological disease that could be causing his symptoms. If you weren't comfortable with your current vet, seeking out a second opinion in person or getting a referral to a specialist in your area may also be beneficial.

With any upper respiratory infection, it's safest to assume that your dog may still be contagious up to a week after symptoms have resolved. So even if your pup is on Clavamox, this rule still applies :)

It could be a side effect of convenia but it is more likely to be the ongoing tooth infection, i personally do not like convenia as a treatment for teeth infections i believe there are much better options such as Clindamycin and Amoxyclav that work much better in mild cases (in severe cases the tooth needs to be removed).

Thanks for using Petco Pet Education Center, formerly Petcoach! Macrolone contains a steroid but is not expected to result in side effects like the ones you describe. The only instance where that medication could result in such side effects is if for example it is causing like gastrointestinal ulceration and anemia. In that case you may notice black tarry stools and his gums may look pale. If that is the case, I recommend that you have him evaluated as soon as possible as that may represent a medical emergency. Otherwise, severe lethargy can be observed with a variety of conditions going from anemia to pain/discomfort. I recommend that you have him evaluated by a veterinarian soon as that degree of lethargy is not expected from that medication and is likely something else going on. Good luck!
