My 5 year old lab who is usually very active has since

Customer Question

My 5 year old lab who is usually very active has since yesterday just lay on his bed and is very lethargic. He doesn't have any weakness in his legs so its not a tick but he is drinking unusually large amounts of water.

Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

Any appetite loss, retching, gagging, lip licking, drooling, or vomiting?

Are his gums nice and pink (not white/pale)? Moist or sticky?

If you press on his belly, does he have any tensing, tenderness, discomfort, or pain?

Could he have eaten anything he should not have (ie bones, toys, plants, chemicals, human meds, etc)?

Any diarrhea? Does his urine look watery/dilute?

Customer: replied 1 year ago.
he is still eating but not as obsessively as usual. His gums are still pink and he has no discomfort when I press on his belly. His urine is quite watery.

Thank you,

Now I have to say that I am quite concerned about Rastas.

If we have lethargy with excessive thirst and watery urine, it raises concerns about his kidney function. At his age, he's not the characteristic candidate for chronic kidney disease but we can see these signs when they have been exposed to toxins (ie antifreeze, human anti-inflammatories, raisins/grapes). And I would note that if we have reduced kidney function, this can make them feel unwell, lethargic, and nauseous (reducing his keenness to eat) as the waste products that the kidneys should be filtering out instead build up.

As well, while not usually causing urine dilution, we can also see his other signs related to other organ issues (ie liver, heart, etc), metabolic diseases (ie diabetes, cushing's disease, addisons's, etc), and also secondary to severe infection or inflammation. We can see it with nauseous dogs (where the overdrink to purge) but his other signs don't quite fit.

With this all in mind, I would warn that we need to tread with care. Ideally, we'd want his vet to check a blood and/or urine sample. This can determine if we have abnormal urine dilution and the bloods can help pinpoint which of the above is an ongoing issue for him. And depending on those findings, your vet can advise you if we have something we can treat and get proper treatment started to get him comfortable and feeling more like himself.

Please take care,

Dr. B.
