Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. I'm sorry to hear that Gelly is breathing heavier today - it is possible she is currently in congestive heart failure, meaning she has fluid building up in her lungs. If she is currently receiving Lasix (Furosemide), you can probably give her another dose of that and see if this helps. If she is still breathing rapidly and with abdominal effort, I recommend having her evaluated by a veterinarian right away. If she is unable to get the fluid off of her lungs, she will be unable to oxygenate her blood and can go into respiratory arrest and die. I hope this is helpful!
