So, I lost Cooper to Cushings related complications in September and in November we adopted Layla, another beagle. She's been a joy and we absolutely love her. She can't possibly replace Cooper, no dog ever could but we love her. Anyway, she's been a great dog and has fit right in with our routine from day one, until tonight. She was extremely agitated, sniffing all around the house, along the baseboards, licking the ground, excessively thirsty and gassy. She was eating everything and threw it all up. Then when I put her in her playpen for the night she ate the wee wee pad. That's when I knew I had to take her to the ER vet. In December we had her boarded while we went to see our son in NC. At that time she was seen by our vet and weighed 24lbs., tonight she weighed 28lbs! 4lbs. in 3 weeks! Her belly is really distended and I'm so scared she has Cushings. Can the symptoms come on so suddenly? With Cooper it was gradual. You guys have so much experience and knowledge, please let me know what you think. The ER vet there was in a surgery and there were complications so I left Layla there to be seen tonight and she will call me after she examines her. It's a great facility and if necessary they will US her. I'm so scared they will tell me to have her tested for cushings. This is the same facility that told me to have Cooper tested.
