Whenever I am stressed or sad Lobo somehow senses I am. When he does he comes over licks and comes in like a hug matter (normally doesn't like). Then Lobo kisses my face or does something funny either one and I am happy and good as new. Other dogs I have been stressed or cried with might to do it for 30 minutes or a little more and just be there until I stop. Lobo is able to cure my sadness or stress just in about 1 minute or 1 second into happiness. Wow Lobo is such a good heart dog!
