My baby Lacy was diagnosed with tracheal collapse at 10 months old. I noticed her coughing and at first thought she had kennel cough so I took her to the vet. I was totally surprised when it was her trachea. They start coughing when their airways close up. I was really freaked out about it for a long time. I didn't want to let her run around the house and get too tired and start coughing. I'd worry about if she was going to be able to catch her breath and if she wasn't what was I going to do to try to save her. But then I thought she's a dog she likes to run around and have fun. I'm still really cautious about it and she's now 16 months old. I let her run around the house now with her brother Cruz who's a chihuahua/yorkie mix, but when she starts panting a lot I stop them from running around the house so she can catch her breath. The worriness never goes away. I'm still really uneasy about it. But I gotta let her have some fun and just be a happy little dog. It's impossible to keep them from playing and running around. But just try to limit her exercise. Don't let her get too tired to where she starts coughing. Hope this has been helpful!!

Good luck to you and your baby!!!
