I have a 2 year old Australian cattle dog mix that’s I thought was in great shape but has an issue with higher intensity exercise. He is great at catching frisbee and will try hard for 10 minutes but then will always stop completely. I had dogs before that would go forever but he’s always done at that point and it seems like his legs get weak and wobbly like he worked way longer than he really did. He has no issues with lower intensity exercise so I was wondering if there’s any issues dogs can have related to lactic acid regulation?
Thank you for your question. It is extremely rare and unlikely to see congenital enzymatic defects related to lactic acid regulation in dogs. If you truly believe this is a problem for your dog, first, I would try to rule out more common conditions starting with a thorough physical examination performed by a veterinarian, full bloodwork, and potentially other testing (e.g. x-rays to rule out hip or elbow dysplasia, etc). However, It is possible that this intolerance of higher intensity exercise is completely normal for your dog and could be a behavioral trait as opposed to a true medical condition.
That is correct. Lactate itself is useful and facilitates transfer of energy in the body. Without lactate, animals and people would be less metabolically flexible.

So we can say that high blood lactate level doesn't cause any problem by itself, and we should treat it only as a marker of possible problems?
