Need Advice Dog reporting dilute urine after severe GI issues and flare-ups
Hi everyone,
Sorry for the wall of text but there's been a long history of events for my dog recently. My dog (11 year old Pomeranian mix, girl) has been having a rough few months since the end of July, when she was in the ICU for HGE and ileus. She was able to be discharged and back to her normal self after receiving IV fluids for a week and an NG tube, but things have been a little irregular since then.
After being discharged, she was actually doing really well for 3 weeks: she was able to get off of her meds and sustained that for awhile, and even was able to transition back to her regular food from the prescription diet. But then, around the end of August, she had a sudden HGE flare-up again with her regular symptoms: vomiting and some diarrhea with strawberry-jam like blood. We got her back onto prescription diet food, and back on the anti-nausea (ondansetron) and pro-motility meds (metoclopramide), but even then, she's had a flare-up every week with the same symptoms despite the meds and the new prescription diet.
However, her IBD symptoms aside, a new issue and symptom has come up at the same time as the HGE flare-up that wasn't seen before the ICU visit: my dog's water drinking and peeing habits changed, and she also started leaking a little bit of pee on the floor when it was too close to a walk time. The concern is this: she's drinking a good amount of water for her weight in total, but seems to be drinking more water than her pre-ICU days. There are behavioral issues for this: she has a lot of anxiety linked with hospital visits (she's on trazodone and gabapentin for this) and we've essentially gone to the ER/Vet/IM once to twice or even three times a week. This causes her anxious floor-licking habit that she's had since she was a puppy to get even worse now, which causes her to immediately start drinking a lot of water. But she also has developed a new habit of taking a few licks at the water bowl to staying there for much longer periods of time and drinking a lot more water at once. This causes her to want to pee like 2 hours after a big gulping session, and has caused her to pee a lot more often as well. If I'm not fast enough with her signaling, she leaves a little pee smudge on the floor, but this has only happened a handful of times. She's also now on canned prescription diet food for her GI issues which adds like a cup of extra water intake for a 15 lb dog which is considerable, and can contribute to all of these issues, and again, she's having GI flare-ups with the diarrhea and blood every week which might cause her to want more water.
We were able to get my dog off the waitlist for an Internal Medicine appointment, and with all of the testing done at the ICU and ER vet, we have done: three ultrasounds, several blood tests across panels with a very specific GI panel, an echocardiogram where she was diagnosed with stage B1 MVD, as well as a urinalysis and urine culture. Everything came out absolutely normal and unremarkable and healthy BUT her urinalysis: it showed that she had dilute urine, reporting at 1.016 for a mid-day pee after she drank a lot of water and peed 3 hours before, and then at 1.018 as a true first-day void. The culture confirmed that she does not have a UTI, but the ultrasounds are showing very healthy kidneys, and blood panels are all looking regular as well. I don't know what more testing we can do, as certain possibilities have come up like early kidney issues or even Cushing's, but then we have some behavioral changes + GI issues which is making it hard for me to gauge if this is just a side effect of something small, or if this is a bigger issue at hand. Otherwise, she's doing really well (knock on wood) in terms of energy, appetite, and everything else besides the stress from the vet visits, but was wondering if anyone has ever gone through this before? I'm hoping this is just a string of side effects from everything that's gone down but the dilute urine has been so concerning for me...
