Horse Veterinary Questions? Ask an Equine Vet.
Hello. Thank you for asking your question. My name is***** will try to help.
Is he still on bute? Did you give him the bute tonight? What antihistamine did you give and when did you give it?
Do you see any puncture wounds indicating a snake bite or do you have snakes in your area? If no snake tooth puncture wounds then probably not a snake bite.
What color are his gums? Are his gums moist or dry?
Ok so if the swelling is fairly equal on both sides he is most likely having an allergic reaction.
The AniHist is not an antihistamine. It is a more for immune support to help prevent allergies. So it will not work for this case.
How much does he weigh?
If the swelling is more on one side then it could be trauma.
Yes, benadryl is perfect.
Give him Five give of the capsules if they are 50mg.
If that does not work in a hour then a equine vet will have to be called to give him a cortisone injection.
You can start cold packing the swelling as well.
My biggest concern is that if it is a severe allergic reaction and is affecting his face it could hypothetically affect his throat and breathing. So a vet could give a cortisone injection to stop the reaction.
Since he is on bute already he may need a gastrointestinal protectant, like ulcergard, because both bute and cortisone affect the stomach lining.
Hi, just checking in to see how Chip is doing and if the facial swelling has resolved.
