...take it to a vet? lol
I hate people who cant control their dogs at dog parks lol so many people screaming "come on lucky! lucky! lucky time to go!" and Lucky is just running around completely ignoring its owner.
And owners of those nasty little dogs who growl and pick fights with everyone and their owner just laughs and goes "oh hes just in a bad mood" or "oh dont worry, he cant do any harm" while their dog is tearing up another one... Aggressive dogs should not be in a dog park...and now Ive been put off dog parks haha
