My 9 month old beagle has been subdued for 2 days. Its very unlike her. My partner has gone on a work trip, left on monday and the behaviour seemed to start the night before he left. Due to this I assumed she was pining for him, but today my dog walker reported she had a very upset tummy. She is still subdued tonight, just sleepy and grumpy - so unlike her, she is usually full of beans and lively and noisy and happy.
