Neither melatonin nor Benadryl is generally considered the best option for dog anxiety, and the best choice depends on the specific situation. Both can have mild sedative effects, but they do not treat the underlying anxiety, and a veterinarian consultation is essential before administering any over-the-counter medication.

Behavioral training, gentle restraint, or professional grooming services are recommended. In some cases, veterinarians may prescribe stronger sedatives or anxiolytics.

The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, representing 3 days (overwhelmed/hiding), 3 weeks (settling in/testing boundaries), and 3 months (feeling at home/bonding) to help owners manage expectations and provide patience, routine, and a calm environment, understanding that anxiety is normal as they decompress from a stressful past. It's a framework for recognizing stress and fostering trust, not a rigid timeline, but it helps owners understand why a new dog might seem timid or act out initially.

When treating sleep disorders, give melatonin 30 minutes before bedtime. Maintain consistent timing to regulate your dog's sleep-wake cycle. Dogs with cognitive dysfunction particularly benefit from regular scheduling. For chronic anxiety, follow your vet's recommended schedule, typically every 8-12 hours.
In those cases, your veterinarian may prescribe medications like Gabapentin (anti-anxiety), Amitriptyline (an anti-depressant), Fluoxetine (an SSRI), or Melatonin (a sleep/calming aid). For pet parents that prefer herbal remedies, CBD, L-Tryptophan, Zylkene, or Rescue Remedy may do the trick.
Lorazepam is a short-acting medication that takes effect in about 30 minutes. Whenever possible lorazepam should be given to dogs in advance of an event that is known to cause anxiety. The drug can also be given at the earliest sign that a dog is becoming anxious.
