My boy is 2 and 6lbs. He stays in his crate all day with no water or food and has had this routine ever since day one. Here lately it seems he has been drinking his water so fast that an hour or so later or the next morning he throws it up not all the water but some. I can hear him some times and it sounds like he is just gulping it all down. In the evenings should I not let him have so much water at once just give it to him like every 30-45 minutes or so?
