Why did my dog puke after using a new bottle of dog toothpaste?
Good job on brushing Lucy’s teeth and I hate to hear that you woke up to vomit! While it is possible that the toothpaste upset her stomach, it could have just been a fluke. Vomiting is due to many reasons: parasites, infection, ingesting something upsetting his stomach, dietary intolerance, toxins, organ disease and intestinal blockage.
At home you can feed her a diet of 25% plain boiled white meat chicken and 75% plain boiled white rice. If this does not make the vomiting stop within 24 hours or if she is exhibiting other signs of illness then I recommend to have her seen by her veterinarian since there are so many causes.
If the vomiting stops, give her a few days and use the toothpaste again. If she gets sick again, then do not use that toothpaste any longer.
I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach.
