Hello. I am so sorry for your loss. The speed this all occurred must have left you in shock, as well as the sadness. There are lots of potential causes and ordinarily I would say your vet is definitely the best person to answer any questions you may have ... but on this occasion, you should get second opinion from another vet. The thing that jumps out at me is the Ibuprofen, which I am alarmed to note you say your vet prescribed as a pain killer for your dog.
IBUPROFEN (NURAFEN) IS POISONOUS TO DOGS.
I put that in capitals so others reading this thread would see it clearly.
I would stick my neck out here and say the most likely cause of your dog's death is a reaction caused by the Ibuprofen. I am not a vet, so cannot say that with any certainty. But you may wish to do some research on the Internet, if you want this confirming.
I hope this information helps.
Hi,thank you. I'm sorry, my mistake! She wasn't prescribed ibuprofen but was given pain killers along with the Benadryl. I'm not too sure the name of it.
Hi. In that case I would suggest you go back to your vet and ask any questions you have. As they saw your dog, they should have far more insight into the circumstances than I have and should be able to explain what most likely happened.
