Thats great That you a have a new found friend in Jake, I'm sure you will get loads of pleasure from him and he will certainly help with your weightloss.
I have 3 Horses along with other farmyard animals, and Mucking the stables out and tending to them all everyday certainly helped me with my weightloss & why I'm nearly at goal so quick.
I hope you have years of fun with each other, You Both deserve it!
Good Luck!!
