Hi there I'm hoping someone can help me, I bought 2 Whippet puppies (Sisters) from a "Breeder". It was only since taking them in did I start seeing things about same litter dogs and litter syndrome. And I'm concerned to say the least, we've had them since Friday evening and they're fine, a few squabbles they play together sleep on top of each other some of the time which is cute if they're not doing that they're cuddling up with us. We keep them in a cage at night and they whine a bit then sleep. All this I guess is pretty normal for dogs (9 weeks) that have just been taken away from their mother, they seem a little withdrawn to us humans sometimes but I'm putting that down to the breed and new surroundings, they do play with us, not like puppies I've encountered before who are nuts. They have bursts of energy and this morning when they were having a run around they really went for each other, I separated them and then they were fine. I'm not an experienced dog owner so need advice, is this normal? Or is this the start of something bad? the last thing I want to do is re-home one, they kids would NEVER forgive me. Thanks in advance P.
