Canine Behavior/Dog drooling


I have a 5 yr old Corgi/Chihuahua neutered male, Charlie. Well socialized, gets along well with other dogs and animals. At one yr of age I adopted a puppy and had no issues with them, they played and got along great. A couple years ago I divorced and I kept this dog and Ex got other dog. I adopted a senior dog and they got along well after dealing with some food aggression initially. I had to put my senior dog down a month ago. Charlie is seen regularly by vet and is healthy. We go on frequent walks around the river and to oet store where he is exposed to other dogs and people. He does well with them. Only issue is fear of things with wheels, especially rollerskates skateboards and bikes, where he does everything he can to get away from them. No fear aggression towards them. That is a quick overview of his past. Tonight I brought home a new puppy, he took one whiff of her and immediately started drooling and foaming from the front of his mouth. I have learned this is due to stress from reading. I have not seen this response from him before....he is interested in the puppy, sniffs and goes into the foaming and get distracted by it. After about five minutes I picked up puppy, while also giving Charlie some petts and reassurance....and placed puppy on floor again. Charlie again shows a wary interest...sniffing but is not relaxed but not aggressive, and the drooling it did while I was holding pup. I put pup in her crate, and Charlie stopped drooling within 5-10 minutes but stayed glued to my side for about half hour before retiring to the bed for the night. I was not expecting this reaction, I hadn't seen it before...though I have not had puppies in the house before but he has met the occasional puppy in pet stores and on our walks. My question is how do I best introduce the two? Will it ease? Is it better to give Charlie pets and reassurance, or to leave him be? They will not be left unattended. By the way, the puppy is a miniature Dachshund.

Charlie appears to be exhibiting a symptom of extreme stress.  He is terrified of this puppy (a dog must be heavily socialized to everything, including puppies, for the first two to three years of life) AND (and important exception), the puppy is female (may be running pheromones, don't know her age but it's still possible.)

Do NOT pick up the puppy in Charlie's presence and especially do NOT try to "calm" him or console him or reassure him.  He does not understand why you are giving him this extra attention and it is, in fact, rewarding his fear/anxiety ("good dog, be afraid").

Since he shows no aggression, this is a non-problem SO FAR.  Keep the puppy on very lightweight house tab; do not crate the puppy to assuage Charlie's fears, you're giving both dogs the wrong signal.  Crates should be used sparingly, an "emergency" tool for house training BUT NOT OVERNIGHT.  Make the puppy a safe and comfortable haven in the kitchen with a strong baby gate (available at Walmart, not too expensive).  When the puppy is outside the gate, hold the house tab (thereby demonstrating to Charlie that he is not being replaced in the social hierarchy.

Verbally reward EVERY APPROACH Charlies makes to the puppy so long as it is CLEARLY NOT FEARFUL.  Give him time.  What he "should " do is begin to ignore this puppy (a statement of social hierarchy) and then, ultimately, they will develop a peaceful relationship, although they may never be "best friends".  When Charlie stuck by you after you confined the puppy, he was in fact further expressing his anxiety and fear but with the clear awareness that the puppy was not at large.

Let's give this two weeks.  Do not interfere with any interaction (unless it is clear Charlie intends to hurt this puppy and I VERY MUCH doubt that will happen.)  Keep control of the puppy with the house tab while she is at large in the house.  Allow Charlie to continue to sleep with you (if he does so now) while at the same time giving the puppy the kitchen (and she WILL whine and bark: buy earplugs lol).  In two weeks, repost using followup so I can see original question/answer.  Meanwhile: walk dogs together outdoors, hold leash of each dog in each of your hands, if a problem develops (Charlie refuses to walk), stop, say nothing, do nothing, wait for Charlie to go forward again and praise lavishly (have a calm "party").  I think Charlie will make this adjustment but it's a huge one and it will take time and patience.
