Hi, thanks for using Petco Pet Education Center, formerly Petcoach! The biggest issue with obesity is stress on the heart and the lungs. Breathing abnormalities while under or in recovery can be huge complications in obese dogs. With that being said I personally do not see higher anesthesia complications in obese dogs over lean dogs. Anesthetic complications are rare and unpredictable and affect all age groups. I hope this helps and I wish you and Maisey the best!
