Among all kinds of dog breeds, bichon is the more greedy one. It eats when it is hungry, and eats when it is not; it eats both good and bad. Like you said, sometimes it even eats feces.
So, what should we do if we encounter this situation?
Let me make a few suggestions for your reference. One is to take the puppy to the pet hospital for a check to see if it lacks certain trace elements? Are there any diseases? The second is to feed food in time according to its dietary rules to reduce hunger and prevent it from eating everything when it is hungry. The third is to look tighter. When walking the dog, the rope is tightened to prevent it from sniffing the stools of other pet dogs. If it is sniffing or preparing to eat, pull it away forcibly, away from other dogs' stools. The stool that it pulls by itself must be shoveled away for disposal in time, and it is not given a chance to eat. This time may be able to make it forget to eat feces.
Raising a dog requires not only time and energy, but also patience and care, to correct its bad habits in time, and to help it develop good habits. As long as you correct it with your heart, this problem should be able to be overcome.
