I would try some red pepper. It won't be fun for him, but I bet he won't dig them up more than one more time.
Abby was really bad about wanting to chew on your hand. I sprinkled some red pepper on it and let her go to town one day. It hit her after about 10 seconds, she shook her head and snorted a few times, got some water and never tried it on anyone again. Was it pleasant for her? I'm sure it wasn't, but we'd tried "no" and putting her in "time out" to no avail. This worked. |
