Hello there, My dear old Sally, is 13 years old, has had both eyes removed over the last 2 years and the other day she had an infection in one of the tear ducts. She has been sniffling and snorting for 3 days or so. The infection seems to have cleared today, but she still is sniffling etc. When I arrived home this afternoon, she was wandering aimlessly around the yard barking and panting. She'd been swimming in her pool too......she wouldn't have a bone that I bought home especially...........Sally and her food....she normally wouldn't miss out! Now she is calm and just lying down in the yard......somewhere she doesn't normally go. Do I need worry? She has been diagnosed with fluid around the heart and is on medication for that. Thank you
