My last dog, a Mastif+Lab, did pretty good, but really didn't settle down until she was almost 3 yrs old. Basically, larger dogs don't really mature until 2 yrs of age.
oosik, how much does your 10 mo-old weigh? (I cannot have a dog that doesn't at least have some Lab in it!)
Our 9 mo-old Pit+Mastif+Lab weighed in at 72 lbs. Previous dog (she ended up being 83 lbs when mature) weighed 68 lbs at 11 mos (when we got her).
Jstpssng, on our property we're never really out of the woods:laughing: (tree climbing, ditch running, water loving, car/truck/UTV/excavator riding Kisha)
