Hi and welcome to YT and congrats on you new baby.
Puppies should have food and water available to them at all times. It is not bad that you give your guy chicken and wellness throughout the day at all. As for nutrical, it is used in cases of low blood sugar, as if they do not eat. I wouldn't give it to him throughout the day just to give it to him. If he's eating well, he should not need to get the nutrical but it is good to have on hand in case. I do not know about Albon so hopefully someone with knowledge about that will come on and be able to answer that for you. At 3 mos old, free feeding is good. I believe at about 4 mos, our vet recommended cutting back to 3-4x a day, and then 3x and then 2x. I know of people who keep food down all the time, totally up to you.
As far as having your little one in a crate, this is mainly for potty training or for the safety of your little one. Hot Rod was only in a crate for as long as it took us to get an expen. Once we got his expen, he had his crate, potty pad, food and water in there with him. I also gave him a chew toy. I like the idea of him being able to have some room but still be contained while I was not home and if I got home late, he would be able to potty and have food and water. Crate training would be something you need to decide on. The expen worked for us and I have read of others gating off the kitchen or a bathroom.
Here is a picture of our expen. I also had a baby monitor so I could hear if something was wrong. It was great when he was in his crate for the week/week and half before getting the pen-I was able to hear him needing to potty. Best of luck to you and Chewy, can't wait to see pictures of your little guy.
