Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
I am sorry to hear you are worried about Kelsey. I am a veterinarian and will do my best to help.
Why was he taking the doxycycline?
How much does he weigh, and how much steroids (how many milligrams) are the pills? Steroids can cause vomiting and diarrhea. They can also cause heavy breathing and panting.
If you look at his gums, are they a normal bright pink?
I see extensive testing was done. Was he tested for low thyroid? Low thyroid, hypothyroidism, can cause heavy breathing and a sad face.
Let me know about his dose of medication, and what else I can answer. Rebecca
