please god tell me someone can help me with this

for the past couple weeks this is what’s been happening:

doesn’t burn when i pee but i’ll get done peeing and a tiny bit more will come out but that happens maybe once or twice a day if at all

slight cramping

slight itching but i have a golden retriever and literally every pair of my underwear has her fur stuck in it so most of the time it’s a hair and then the itch goes away but i’m starting to wonder if its something more because of this other stuff.

edit:

she gets a groom and a bath twice a month. that’s $120/month and i don’t want to spend even more just to experiment whether or not it’s her fur because 3/4 of the time i itch my finger comes back up with one of her hairs on it
