I recently purchased at Berners for my 12 year old daughter. It took 7 years of begging. He is adorable but is extremely mouthy. Even the vet mentioned he seemed to be more so than usual. We have been working on it daily but this evening he got aggressive over some ham we were using for treats to train him with. He learned to sit first day we had him (8 weeks) but he grabbed the bag and ran under the bed. He was not about to let us get the bag from him. I reached under the bed and he actually growled and the bit me to point there was a puncture not the mouthy pup type it was a food aggressive growl and bite. We feed him 3x a day and even put hands in food to help prevent food aggression. I am concerned about this behavior. He can get the puppy crazies too but this was different. I give him alternatives to chew and if it gets out of hand we give him a time out in isolated area (not crate) that usually curbs behavior. He is still small and is on his way to being huge so I am looking for help or advice or anything to help me with this. I had 2 other Berners and this puppy is much more aggressive than my other two and I am quite concerned.
I have a 6 month old Berner girl. She has not displayed food aggression, but has been known to steal... She does get over excited aggessive while playing and we wanted to nip that out since there is a 9yr old daughter and her friends in the house. We do things to show we are in total control of food and everything to assert humans as the pack leades. Putting your hand in food is good, we also do that. We have had her sit with a relase command for food and treats since day 1 (8 weeks). We also fed her from our hands intermitently and we take away the food away while eating and then giving it back (sometimes feeding from hand then) . Since your pup is showing signs of food aggession, you might need to feed from your hands now. He needs to know you control the food and know that aggrssion is not acceptable. Smearing a thin layer of cream cheese on your finger were the pup has to learn to lick off the food from hand gentely not bite/nibble it off. I started my pup in petsmarts training class at about 14 weeks and it has paid off.
