Welcome! I am Dr. Altman, a licensed veterinarian and happy to answer your questions today.
It sounds like she ingested 83 mg/kg dose. Did she bring any of it up when she vomited?
yes a little bit
The good news is that ranitidine is used in veterinary medicine for various things. It is dosed usually at 1 to 2 mg / kg twice a day for gi upset. The dose that ingested isn't going to be of great concern. The veterinary drug formulary has this statement "In laboratory animals, very high dosages (225 mg/kg/day) have been associated with muscular tremors, vomiting and rapid respirations". So you can see that the dose she got is 1/3rd this dose when compared. At this time, no specific therapy is needed besides limiting water/ food this evening and then tomorrow starting small frequent meals of white rice and boiled chicken (hourly 1 tsp then as she is holding it down increase the volume while reducing the frequency)
I would also advise not repeating the milk. Most dogs are actually lactose intolerant and it can cause further upset to the gi tract
But nothing else tonight to allow the gi tract to rest and keeping her quiet then small amounts of water in the morning followed by small amounts of food
If the vomiting continues with this then I would advise a veterinary examination
ok good so tomorrow do the rice and boiled chicken
Just small frequent amounts to test the stomach
It is bland yet bulking to the gi tract to minimize vomiting/ diarrhea
And if she does well you increase the amount while reducing the frequency
Can I assist with any additional questions or clarify anything?
nope i think that was it but thank you very much! You have made me fell better!
That is fantastic, glad I was able to assist in resolving some of your fears. That makes it all worthwhile :)
Good luck to you both!
