We are bringing home a new puppy; and are worried our 5 year old staffie may become aggresive towards it when we are not around. Can anyone suggest anything? The pup is a French Mastiff which will outgrow the staffie; although our staffie has been desexed and is a male; the new pup will also be a male. HELP
I would have suggested getting a female. I would also suggest keeping the puppy in a crate when you are not home. Will the new puppy also be "desexed". I would suggest that also and as soon as he turns 6 months old.
The main thing you need to do is to not allow them to be left unattended together. Crating or placing them in seperate rooms is best to insure nothing happens between them while no one is there to intervene.
