hi people, i got my dog. its a chocolate labrador. he is very cute and a very nice pet. but he keeps biting my finger for some reason. i need to know why he is doing this. and i am crate training him. the only problem is he doesnt like being in his crate. he keeps barking when i put him in his crate. he needs to be toilet trained. can anyone tell me a good way to do this. he is one and a half months old. can i put a collar on him and take him for very short walks ? there are many street dogs here who bark when i take him out. what do i do? please guide me. vidyashankara.
