I would pay lots of attention to the animals love taking dogs out for walks even tho I got two cats who can literally walk themselves and feeding them is simple. I feed my cats every day one serving because one of my cats is getting fat so keeping a moderate amount of food is best for the pets. Not to over feed them. And with me any size animal is fine they might get me spook for a moment but once I see that he/she is a good dog/cat I'm sure it'll be fine for seeing too they well being. Plus, I inspire to become a vet. I'm going to college learning biology pre-vet. I'm on my third year. After, JSU I'm going to grad school to get the real Vet experience.
