hi everyone i had a couple questions for you knowledgeable dog owners. my dog is good with the cage at 5 months and he doesn't whine when hes in there so what we have kind of routinely done is whenever we eat we feed him and put him in his cage so he doesn't jump and beg. the reason i bring this up is im not sure if he doesn't feel like part of the family while we eat. I am not sure if its ok to do this or not. another question i have is can i give him some of our food cuz i feel bad he doesnt get to enjoy the food we eat and only gets to eat dog food. everyone i know gives theyre dogs people food and i just want to make sure it wont hurt him. and also we give him 3 cups of science diet large breed puppy food but when he eats he devourers it in like 2 seconds and i feel like he isnt getting enough food but on the bag it says 3 cups. he is a boxer hound mix hes 27 pounds and he is about 5 months am i feeding him enough? any info would be great.
