Question: I have been raising a Rottweiler puppy since she was 1 week old. I’ve worked at a small animal practice for 5 years—and a breeder came to us with a 5 day old female puppy who’s hind leg was bitten off just above the tarsal joint by another dog– the breeder wanted her euthanized, but I asked for her to sign ownership to me and thankfully she did. She is now 11 weeks and I’m getting discouraged with her behavior. She continuously bites at your hands, arms, ankles, neck, etc., when she’s getting attention/ affection and being (gently) petted;

Question: Hi Dr. Yin,My female 18 mos old ACD is getting better and better about responding to my commands when off leash. The biggest problem is her chasing of bikes (and sometimes runners). I think they startle her and then move so fast that she goes immediately into prey mode. How can I learn to teach her to ignore them? or at least stop and wait for my command when something so exciting is happening.thanks! Gwyn from Marin Answer: Gwyn, while many dogs chase bikes and runners (see article on Why Runners Steer Clear of Dogs), it’s definitely no surprise to

Question: I am crate training my 4-month old Yorkshire Terrier to hasten his potty training. I take him out on schedule and he was responding during the first couple of weeks. I subsequently added an exercise pen into the mix so he can play safely without supervision. Lately, however, I noticed he no longer wants to do his business on his designated area and would now prefer to go in his exercise pen instead. Is introducing the exercise pen a bad idea? Many thanks.-Wally Samonte, NV Answer: While some pups are good about “holding it” when in an X-pen, many

Question: My Havanese puppy loves to nip my heels and the backs of my legs. When I stand like a tree, he pulls my jeans or nips my legs and then stops. I praise him and give him a treat when he sits and stops pulling at my jeans or nipping my legs. However, no sooner do I move again, he repeats his behavior. He also likes to nip my hands and arms. I am trying to teach him to kiss me instead of nip me but that is not working so well either. When he kisses me, I reward

One of the most trying tasks associated with having a puppy is potty training. Some people think that potty training is as easy as just keeping the pup on a regular eating, drinking and potty-outing schedule where he is taken out every several hours. Here’s what’s really required for foolproof potty training—it’s not an easy task. This rigid routine must be carried out consistently for several months and without accidents for several weeks before it’s set.

Question: Dr. Yin, I was wondering if you could offer some advice about dogs mounting other dogs. I have a 10 yr. old fixed Standard Poodle who gets very excited when he greets another dog and he ends up mounting the other dog. Male, female, big dog, small dog – it doesn’t matter. I would just like to know why he does this, and how can I stop it. Thanks for your time. Pennie Answer: Pennie, you’re not alone. Many neutered dogs perform this embarrassing social faux-“paw”, not because they’re being amorous or trying to dominate, but because they are
