Belgian Malinois mix? Questions

I would not use an ecollar. There was only one trainer who was able to help a huge presa I adopted from shelter from having to be being put down, he did not charge me anything and his advice worked. I do not have Cane Corsos but he breeds them.
If you have training questions email him http://sanroccocanecorso.com

Bottom line is this guy trains for police and knows tons of K9 trainers. Ecollar can spook them and should not used 99% of the time. I had ecollar trainer I paid 2,000 in Fairfax Va it helped for the first month then back to same old.
