Help! My 17 month old, male, neutered, Great Pyr is extremely food aggressive (w/ people and other 2 family dogs). I thought we were doing better but today he almost bit me. He came to me at 10 months and brought the problem w/ him! Ops, I put JetsMom where I should have put "food aggresions". Sorry, I'm new...
You need to start training him to be gentle, and teach him that hands are not for biting, smear a bit of peanut butter on your hand and let him lick it off, if he bites all the time, don't try this, call a behaviorist, but if he'll lick the peanut butter give it a try, this teaches him to be more gentle with hands. Then when it's time to feed, place his food bowl down empty, then with your hand, place food in there little by little, one handful at a time, encourage him and try to sooth him, don't leave your hand in the bowl though, this should teach him that you're not going to steal his food. Be very careful especially with such a large dog, I had to do this with my Dachshund as she was growing up but she's alot smaller. If he's very roudy, you may want to have him leashed and an assistant if he knows the sit command utilize it if he gets impatient. When he starts getting a little used to the idea, go ahead and fill up the bowl and pet his head if he lets you sort of go near his muzzle (not in his mouth!) and move his food around, praising the whole time, this step will take lots of time though, approach it slowly and take caution, but don't be afraid. As for him being food aggressive with your other 2 dogs, I recommend you feed them all at different times, but for example if the other 2 are fine eating at the same time, feed em at the same time. Another rule of thumb here is make sure they all have their own bowl, this will help alot. And if you have to feed them at seperate times (it can just be like one dog finishes eating, then it's time for the next dog to dine)have the one(s) that are not eating elsewhere, in the yard, etc. supervised of course. Hope this helps, and it works out alright, but remember sometimes dogs need a professional behaviorist if it gets that far (hopefully not).
First of all I would start with NILF. Secondly don't feed all 3 dogs at a different time, feed them all at the same time just different parts of the house. If you feed them at different times one will think they are being "left out" and may cause it to be worse. Work with your pup with it's food aggression. Before you feed him make him sit and wait til you give the command. While eating pet him on his back, see how he reacts, then to his head. Slowly work your way to his face, doing this will get him used to being touched while eating. If you can try getting or making a fake hand, and while he's eating pet him with that and try to "take" him food. The more you work with him the better. As far as the food aggression goes with the other dogs, you may be in for a life time of feeding them in different rooms.
-he is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of
Everyone else offered good advice, I just wanted to throw something else in. When our Golden Retriever started showing food aggression towards my daughter, I also got great advice from everyone on here. His trainer also said to throw some nice treats toward him when he was eating. That way he associates you being near his food dish in a good way. That has also helped our situation.
