Hello, my name is***** and I have over 20 years of experience as a veterinarian. I am sorry to hear that 20 pound Buddy ingested a little orthoboric acid (also known as Borax or boric acid). My apologies that you have been waiting for a response. Nights can be very busy and I responded as soon as I came online and saw your questionOrthoboric acid (sodium tetraborate) is a fairly safe chemical. It is a desiccant, which is how it works on insects, but a dog would have to eat huge quantities to even see stomach
upset and that would be the only thing you are likely to see. It is likely Buddy will have no effects, or very mild effects from taking a few licks .You should not need to do anything unless you see symptoms.If he seems to have mild stomach upset you can feed a bland homemade diet
consisting of 1/3 boiled, lean hamburger or boiled, white, skinless chicken
, all fats and juices drained off the meat, and 2/3 white rice.Signs that things aren't going well, and he needs an immediate veterinary visit, are vomiting, a tense painful belly, lack of an appetite, a fever (more than 103.5F rectally) and lethargy. But if he didn't eat much that shouldn't happen, no worries he will very likely be fine.Please let me know if you have any further questions.
