This is Dr. Christian. Welcome to JustAnswer.
What situation are you trying to treat? How much does Ziggy weigh? Does he have any other medical conditions or take any other medications? What else have you tried?
he has small red bumps on his body mainly around his neck and belly, he seems to be itching all over though, i gave him a bath with 4% chlorhexidine shampoo earlier, he has no medical condotions and weights 20 lbs
It certainly sounds like an allergic reaction. Cetirizine isn't very effective in dogs in most studies but benadryl works very well. You can give 25mg of benadryl every 8 hours for the next 24 hours. It might make him sleepy but is safe. If he continues to have problems or starts to worsen then he might need a steroid injection from a vet.
we live kinda far away from a store and don't have benadryl would the cetirizine help at all until morning and is it safe?
what about metacam? i have some from when he had surgery
Metacam is a pain medication and won't help this situation. I don't recommend ceterizine. It has more side effects and can be dangerous. Perhaps a neighbor has some benadryl (diphenhydramine)?
ok making some calls thanks
You are welcome. Good luck.
