When I went to her home, he barks and keeps his distance. Seems like a 'wood' dog. Tough to look at tongue but seemed pale lavender. I had owner send me a pic today when he's calm and she got one from the side and still seems that way but along the lateral edge - it could be a darker pink right on the edge. (pic with mouth closed and lip lifted) She did change to raw a month ago and we added in Renal Support from Standard Process. He wasn't a hot or cold dog, likes couches, beds. He was so scared of me but I had written the pulses were more wiry than slippery and weaker on the right. He has good and bad days since diet change a month ago per owner. Today she saw him drinking the whole bowl and then is frantic to get out and has occasional accidents. He loves to eat his new diet and both dogs like to eat grass, mulch, etc in yard. A recheck urine this week showed a pH of 6, SpGr of 1.050 (assume first urine of day), only 2 crystals on slide. no signs of infection. So, he can concentrate urine, not an obvious crystal/infection issue. I'm torn on the 'heat' signs of drinking a lot vs deficiency. Please help:) I'd like to do some herbs but not sure what.
