How often can a 25 lb dog have Benadryl?
Every 8 to 12 hours, so no more than 3 doses in 24 hours. If one dose doesn't seem to help, don't double the next one. Call your vet instead, because the problem may need a different medicine.
Watch for these side effects
Expect some sleepiness. Call your vet if your dog becomes very agitated, pants hard, has a racing heart, can't pee, or vomits repeatedly. Wide pupils, tremors or seizures can signal an overdose. If you see them, call ASPCA Animal Poison Control on (888) 426-4435 or go to an emergency clinic.
Always confirm the dose with your own vet, especially if your dog has a health condition or takes other medicines.
