If you are feeding drying food, she may need more water to help digest it. Also, that breed is very energetic. Some dogs only seem to drink with owners present and drink very little in the day when alone. If it seems excessive (you are always filling up the bowl) give her 8 oz at a time and see how long it takes her to drink that and keep up with how much she consumes over a 24 hour period. You can then take that to your vet for them to check and do a urine sample or blood test to make sure there is no infection or diabetes.

    IT's definitely abnormal. excessive drinking and urination can be cause by various conditions such as kidney failure, diabetes, liver disease, urinary infection and uterine infection, i strongly recommend taking her to the vet ASAP in order to get it checked and treated.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Puppies and kittens drink a lot more water than adults. A general rule is that a puppy needs about 1/2 cup every 2 hours and when she gets older about 1/2oz to 1oz per pound of body weight per day. More if she is very active. It does seem like 23.5 oz per day is a lot. If Frankie is very active then it might be ok. If she isn't I would have your Vet run some blood work to check her kidney values. I hope this helps and I wish Frankie the best!

    If she is going through more than a bowl of water a day, then this is considered excessive. If she is also peeing more then this could be a sign of a UTI, and you should get her checked by your vet and subsequently treated. However if she isn't having accidents or going potty more than once pet hour, then this is likely a normal intake for her and not concerning for any underlying illness or disease process.
