Can I Give My Dog zzzquil?

There is no definitive answer to whether or not it is safe to give your dog Zzzquil. Zzzquil is a brand name for an over-the-counter sleep aid containing the active ingredient diphenhydramine.

Diphenhydramine is a first-generation antihistamine that can cause numerous adverse effects in dogs, including sedation, lethargy, ataxia (wobbliness), and changes in heart rate and respiratory rate.

Additionally, Zzzquil can be toxic to dogs at doses much lower than those typically found in humans. If you are considering giving your dog Zzzquil, it is important to speak with your veterinarian beforehand to weigh the potential risks and benefits.

Is Zquil harmful to dogs?

ZzzQuil is a brand name for an over-the-counter medication made from antihistamines and diphenhydramine. It is marketed as a sleep aid. While it is not specifically harmful to dogs, it can cause adverse effects such as sedation, dizziness and dry mouth. As with all medications, ZzzQuil should be given to dogs only as directed by a veterinarian. 

What can you give a dog to make them sleepy?

There are a number of things that can be given to a dog to make them sleepy. One of the most common is melatonin, which is a hormone that helps regulate the body’s internal clock. It can be found in pill or liquid form, and is usually administered two to three hours before bedtime.

Another option is a medication called Benadryl, which is made from diphenhydramine and is used to treat allergies. It can be given to dogs in tablet or liquid form and is most effective when given an hour before bedtime. As with ZzzQuil, both of these treatments should be given to dogs only as directed by a veterinarian.


It is generally safe to give dogs ZzzQuil as a sleep aid, as it is non-addictive and does not contain narcotics. However, it is always important to consult with a veterinarian before giving any medication to a pet.
