I have two sister beagle-dachshund mixes and they both have issues. There are 2 things i really need advice on, if you can offer that. 1) even when the food bowl is full, they will go to it and try to overturn it, or dig at it or shove it with their nose. They still eat from it though. What does that mean and how can i make it stop? 2) they constantly growl and fight with each other and get into nasty fights. We’ve tried some stuff, it hasnt stopped and its getting old. Any advice?
