Why is my dog sick, breathing weird, vomiting, and straining to pee?
Hi, thanks for usnig Petco Pet Education Center, formerly Petcoach!
I am sorry your dog is sick! It would be helpful to know your dogs age and if she is spayed. Also if she is having trouble urinating or defecating?
Anytime an animal is not breathing normally it is an emergency. Sometimes the breathing can look abnormal when they are in pain or have a fever but there are more serious causes for trouble breathing that are life threatening: heart failure, pneumonia, pleural effusion, cancer. The abnormal breathing alone is a reason to take her to an emergency room now.
If you mean she is straining to urinate and is NOT passing urine, that is also a life threatening problem and see should be taken to an open emergency room. Causes of being unable or urinate are most commonly from a bladder stone stuck in the urethra or a bladder tumor. When dogs strain to pee they can vomit and pant due to pain
If she is straining to poop, then that likely means she has diarrhea and feels the urge to go but doesn't have any stool to pass. Since she is also vomiting she could have an upset stomach from: intestinal parasites, viral or bacterial infection, ate something gross, food change, new treat or table food, pancreatitis, toxin ingestion.
If she is straining to poop then that can wait for your vet to open. Trouble breathing and urinating shouldn't wait.
I hope this helps and I wish you all the best!
