Our 10 lb Chi had a complete breakdown after we lost older dog, went thru grief, depression therapy with Karen Prior institute for her and after several med tries found Xanax has really helped. She gets the liquid compound in an oral syringe 2x daily for the rest of her life. Also for short term anxiety we use Adaptil Spray, it's the pheramone of doggy nursing mothers. Spray, wait 15 min and they can be around it-blankets-dog clothes, etc. Also Thunder Shirts really help. This is weird sounding but thunder storms bother them because of the static electricity in the air. We put an unscented fabric softener sheet on then and it helps due to reducing static electricity in the air touching them. Strange but true.Hoping for a blessed new year for all.
