It's crucial to contact your veterinarian immediately. Even if your dog seems fine now, Zantac (ranitidine) can be toxic to dogs, and the effects might not be immediately apparent.
Here's what you should do:
1. Call your vet right away. They can assess the situation and provide guidance.
2. Be prepared to give them details:
* The specific amount of Zantac your dog ingested
* How long ago they ate it
* Any symptoms your dog is showing (even if they seem minor)
3. Follow their instructions carefully. Your vet may advise you to bring your dog in for an emergency appointment or suggest specific actions to take at home.
Don't wait to see if your dog gets worse. It's better to be safe than sorry.
