Why do people like dogs so much?

My cat is normally pretty lovey, but she's been acting up recently. She still cuddles up and starts licking my hand when I pet her, but then she just bites me randomly. Is this normal or is there another reason my cat has been doing this?

Are there any home remedies for eye discharge in dogs? My 6-year-old retriever is getting this kind of greenish gunk coming out of her eye. It doesn’t seem to bother her at all, she isn’t pawing at it or anything, but I’m also kind of worried it might turn into an infection. I don’t know, what should I do for her? I’ve been wiping the discharge away whenever I see it but it keeps coming back.

My ex told me I was an awful kisser, but this quiz she was lying! What did you get?

I have a 5-month-old puppy and I’m really overwhelmed with potty training. I feel like I’m taking her outside every hour to try and avoid accidents and half of the time we just end up staring at each other while she whimpers. I just have no idea if I’m doing this right or not. I’ve watched videos and stuff about rewards and reinforcement but it just feels like nothing is really sticking? Any advice?

I want to become a bartender but I don't know how to land my first gig. Every bartending job wants experience but where do I get that experience? Are bartending classes or training worth it?
