Our Jack Russell has developed breathing problems
Our 13 year old Jack Russell has always been an active dog. She still does lots of running and hunting, but has started having some changes in her breathing at times. She has been sneezing a lot, snorting,and also having some wheezing at times. I took her to our vet and he gave her a steroid shot and antibiotics, which helped for 2 weeks and then the symptoms returned. Now I am noticing some spots of bloody mucus at times on the sheet where she sleeps. Does anyone have any idea what is going on? Is it her age, or allergy?
