Hi everyone. We've had dogs before but these are our first puppies. So anyway a couple days ago we got 2 five month old purebred red kelpies. Brother and sister. They're both healthy and all and at first there were no issues with them eating but we have noticed that when they are playing the girl will really bite into the boys neck or ear and hurt him. Also, when they eat at first they were fine and then the girl started trying to take the boys food and now it's at the point where he won't even eat she just has to look at him and he'll walk away and leave the food. I stayed home today to try to sort it out and the only thing I could get him to eat was an egg and I had to put him in the laundry with her outside and feed it to him. I'm not sure why she is doing this as they have been together all their life and it could be a real problem.
Any help would be much appreciated
Thanks
