Like the title says, Ranger has lately been drinking a lot of water. After maybe 5 minutes of playing, he will go and drink tons of water (1-2 minutes straight sometimes). This is his only symptom of anything (if it's a symptom.) He still acts normal, plays like normal. He has a red spot on his stomach, but that has been attributed to slight grass allergies, and now that the grass has finally died that should start disappearing until the grass turns green again. I will ask the vets at work about it, but with a lot of water drinking as the only symptom, that could mean many things. Are there other symptoms I should watch out for that maybe I just haven't noticed that can indicate anything? He is a brittany who is 50lbs, but that is mostly muscle on him according to the vet, and he is about 2 inches taller and longer than the breed standard, so he's already a big dog. Anyways, anything you can think of would be appreciated!
