Hello! i have 2 brother Nigerian dwarf goats (both are whethered). recently one of them will strain to pee but only occasionally and usually only after he’s already urinated a lot. He doesn’t do it after every-time he urinates either. we recently changed their diet from 1/4c of BOSS, purina goat grower and alfalfa pellets (1/4 c in total bit of each) sweetlix minerals, baking soda, and orchard hay (free choice) now we switched to about 1/3c of ONLY timothy pellets (with no other additives) and less that an 1/8c of alfalfa pellets (with no additives). We were told to take the baking soda away and to pulse dose ammonium chloride (feed for 1 week out of the month) by another goat owner. i’m taking to the vet in about a week to get them both checked out but i’m just wondering what it might be. they are also the only two goats so i don’t think they’re just being gross boys. I’m worried about stones but he’s not swollen, his urine is a normal color, he doesn’t strain all the time ( not even everyday) and he’s not acting like he’s in pain. Thank you in advance.
