Hello. I new to the forum and wanted opinions on what is happening to my 2.5 year old, full breed Labrador. When we throw the ball (absolutely ball obsessed, for good or bad) she goes ALL OUT. When I say all out I mean she runs as fast as she can go, 100%. So, we used to play with the ball longer, now we can only play with the chuk-it for around 15-20 minutes before she is super exhausted and she typically pukes later and it's the only time she poops soft serve. She is incapable of even managing a walk around the block after we play with the chuck-it. It appears that she is getting worse as well. We used to play ball for 30-45 minutes and she never puked before. I don't think this is normal as she is only 2.5 years old. I know about labrador exercise induced collapse. She definitely has experienced that. However, every time I have taken her to the vet, she is tested healthy. I don't want her to be a couch dog or inactive as I am very active and want her to be happy and outdoors. I worry about her long term health and quality of life. Anyone experience the same thing?
