🐾 Tessie-A New Helping Paw for Anxious Dogs 🐾
Good news for dog parents: as of May 6, 2026, the FDA approved Tessie (tasipimidine oral solution) as the first ever drug cleared to help dogs suffering from both noise aversion and separation anxiety. (fda.gov)
What are noise aversion & separation anxiety?
Noise aversion: fear reactions triggered by loud sounds-think fireworks, traffic, or thunderstorms. Dogs might pant, tremble, hide, or bark. (fda.gov)
Separation anxiety: when dogs get stressed, destructive, or vocal when left alone. (fda.gov)
How Tessie works:
Its active ingredient, tasipimidine, is part of the alpha‐2 adrenoceptor agonist family. That means it helps calm that fight‐or‐flight nervous system response when a dog is scared or stressed. (fda.gov)
Sensitive timing: give the dose about one hour before a known stress trigger (fireworks, leaving home). (fda.gov)
Best when given without food-eating beforehand can slow its absorption. You can offer a small treat so the dog accepts it. (fda.gov)
You can use it multiple times a day if needed-up to three doses every 24 hours, with at least 3 hours between each. For separation anxiety, generally used twice a day. (animaldrugsatfda.fda.gov)
What owners should know:
It's prescription‐only. A veterinarian should assess the dog, rule out other issues, and determine if Tessie’s right. (fda.gov)
In studies: Most common side effects were mild-vomiting, lethargy; for separation anxiety, also diarrhea in addition. (animaldrugsatfda.fda.gov)
Not meant to replace behavior training-best when used with training and environmental strategies. (aaha.org)
When will it be available?
Tessie is made by Finland’s Orion Corporation, and in the U.S. it will be distributed by Zoetis. (orionpharma.com)
Expected rollout in the U.S. is mid‐2027. (orionpharma.com)
If your dog shakes at storms, hides during fireworks, or loses it when you leave-they might finally have a treatment that helps. Talk with your vet to see if Tessie could be part of your dog’s calm‐down plan! 💙
