16 week old Yellow Lab Tricks



16 week old yellow lab does a few tricks.

EDIT: Since we posted this video many people have suggested that Jack is overweight or that we feed him too many treats. The treats were ONLY given for training. His weight is due to him being on Prednisone for Puppy Strangles at the time this video was shot. He is not then or has ever been overfed.

Jack is of the English Lab variety.

As for his training we had him enrolled in “puppy school” and this taught us how to teach him. He is a quick learner and was often able to complete a trick after being shown a few times.

As of now (March, 2009) Jack is almost 2 1/2 and is still a beloved member of our family.

Thanks for your comments and well wishes,

dua (prayer) – Lab pe aati hai dua…



One of the masterpieces by Allama Iqbal includes the nazm which goes – “Lab pe aati hai dua …” It is a kind of dua (prayer) which asks God to bless us with some beautiful things like love for the entire world, love for one’s country, love for knowledge that becomes a blessing for the entire mankind and lastly, compassion for all human beings.

This soulful nasheed has been sung by melodious but a little unheard singer — Siza
