Hi Hernan and
to the forum,
I have had Gucci (my one and only Havanese, and first pet EVER, so I relate with you on that account) on a fresh meat/homecooked diet for about 2 years now.
I do feed her mostly chicken, either chicken breasts which I will cook every few days (bake, pan, boil) OR I will also put the whole chicken in a pot and boil it for an hour or two and then I'll pull the meat off the bone, use the stock to make soup for us humans, and toss the bones out.
I'm curious, why you want to feed the bones? I'd be afraid to, even though I have read some places about feeding them crushed/soft chicken bones, I still always worry that that one 'tough' or dangerous piece would end up in their intestines reaping havoc.
Since I use the smaller chickens, the meat feeds her for about 3-4 days, depending on her appetite. I've had a really hard time with getting her to eat veggies and fruit, so I have to mix supplements into rice cereal or risotto..or brown rice or here lately, I've been feeding her quinoa with the supplements/vitamins that she's lacking from her bull headed-ness to not eat veggies (I've tried and tried, but she'll just eat 'around' them, lol)
I did find one for a fresh meat diet that works well, I'll post the link in a bit, I just got called into work, so I've got to cut this short for now.
I can put together some helpful links for home-cooking if you are sure you want to go this route. I personally believe I can do a better job than the kibble companies
