My puppy is now 13 weeks old and is the typical, rambunctious, aggressively playful with nipping that we work on. He is a high energy breed. However, this the second time taking Credelio and he was extra excitable and anxious both times. The side effects do say it can cause neurological problems but it is associated with seizures and paralyzing symptoms. Not what he exhibits. He has urinated more and has had more accidents both days he took it. Has anyone experienced this?
