Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.
Again I do apologize that my colleagues could not aid you sooner, but can you tell me:
How long has Jax had these signs?
Any coughing, sneezing, congestion or discharges from his eyes or nose?
Any retching, gagging, or vomiting?
Is he drinking and breathing normally?
Are his gums pink or pale/white? Moist or sticky?
If you press on his belly,does he have any discomfort, tenderness, or tensing?
Could he have eaten something he should not have (ie bones, toys, plants, chemicals,etc)?
