Do you notice your dog acting stressed or anxious? Symptoms of dog anxiety can range widely, from excessive yawning to more obvious signs like trembling. If so, it may be time to talk to your veterinarian about dog calming treats or supplements.
Calming treats for dogs can be helpful for stressful situations, such as fireworks or thunderstorms. Or, if the anxiety is ongoing, a dog calming supplement along with behavioral therapy and modification can make all the difference in promoting relaxed and balanced behavior in your pup.
The best calming treats for dogs are from a trusted brand, are effective and easy to administer, made from quality ingredients, and come recommended by your veterinarian. To help you choose the best dog calming treats or supplements for the job, our panel of veterinary experts selected their top picks in several categories.
What To Consider When Buying Calming Treats for Dogs
Look for calming dog treats from a vet-trusted brand known to use research-backed ingredients, speak with your vet, and consider how quickly you’d like the effects to kick in and how well your dog will readily accept a particular type of treat or pill.
Brand Trust
Choose dog calming treats and supplements made by reputable brands with research behind their products, including clinical trials backing the effectiveness and safety of their dog calming products.
It may be helpful to look for the National Animal Supplement Council (NASC) quality seal, which indicates the calming aid meets or surpasses the organization’s quality control standards.
Ease of Administration
Dog calming treats and supplements come in various forms, including chews, powders, pills, and capsules. Consider which type will be easiest to administer for your dog, especially if it’s recommended to be given daily.
If your pup prefers tasty treats, a calming chew for dogs may be the best choice. Calming dog supplements in powder form can be easily mixed into your dog’s food, and a dog calming pill or capsule can be hidden in a pocket-style treat.
Ingredient Quality
Ensure that any dog calming treats contain high-quality, well-sourced ingredients that are easy to digest and won’t trigger a reaction from known food intolerances in your pup.
The active ingredients and their claims should be backed by research and considered by your veterinarian to be safe and effective for your dog. Commonly used ingredients in dog calming treats and supplements include amino acids, such as L-theanine and tryptophan, and plants such as chamomile and ashwagandha.
Time to Effectiveness
Think about what you are using the dog calming treat for, whether it’s a one-time situation like a visit to the groomer or for an ongoing issue like dog separation anxiety.
That’s because some calming products start to work quickly (e.g., within 30 minutes), while others work best with consistent daily use over several weeks.
Your Vet’s Input
Always check with your veterinarian to ensure a calming dog supplement is right for your dog’s age, health, and situation. Follow all dosing guidelines and talk to your veterinarian about any concerns about side effects.
