Hi there,I can help but can you tell me:what sort of dogs they are?is your seven year old neutered?does your older dog have access to your sofa, bed etc?Are there any other people in the household?Is your older dog used to being with you a lot of the time? Are the dogs both boys?Does he have food down all the time or are there set mealtimes?
To put your mind at rest, if your older dog is generally a friendly non aggressive dog he is very unlikely to hurt the puppy.He may well let him know who is boss using body language/noise You mustn't make too much of a fuss of the puppy,let your older dog know he is still no.1, this is important for your older dog and puppy. Pup needs to know older dog is boss. You must let the puppy out for socialisingt,ensure the older dog has a safe 'refuge' he can go where the pup can't follow.You have to let the pup out asap for the sake of both dogs, your puppy needs socialising as much as possible, not in a cage on his own.How old is the puppy?Can help you lots if you can give me some more info. Is your older dog showing any interest in the puppy at all or is he trying to get away?Is he showing any aggression?It's a big disruption to his routine, you have to manage it carefully if they are going to get on, so many people don't realise it's not easy bringing apup into an older dogs' household.Whatever you do let the puppy out at least 20 mns every hour,he isn't learning anything in isolation.Don't panic the older dog will pick up on that and think there really is a problem. I introduced a confirmed cat hater to a cat at the age of 8,they lived in peaceful tolerance of each other, a pup should be alot easier .What does your older dog actually do when faced with pup?Are you holding the pup in your arms and pushing it towards your dog by any chance??More info needed, fire away. I'm a vet nurse with 26 years experience, I specialise in dog behaviour , this can be sorted out no problem ok.
