I think you should be asking not just what they are going to eat, but also include getting along with them.
When you ask this question, it means you should not have started fostering yet. Congratulations on asking the question first, it's the right thing to do.
First of all, I want to tell you that dogs are the best life partners of human beings, and they are one of the most loving animals. Most people think that we are the ones who raise them (I don't use them, but it's actually because of their high spirituality), but in fact, it's them who dedicate their whole life to us with love and joy. So before you decide to start buying or adopting, be mentally prepared and aware of them.
Their life span is usually 10 years, up to 15 years. They eat, drink and shit every day just like humans. And they are very cognizant of their owners, so once you decide to live with them*** you have to be prepared - not to leave them, which is their absolute commitment to our birthright. When we give our love to them, they will definitely give it back to you several times over.
Now let's talk about how to raise a dog for a moment
As another respondent said, they are omnivorous, and since you're a vegetarian, there's no problem giving them vegan. My dog, and my baby, is called "Pudding" and he is a small dog. When he was little, he needed two meals a day because he was growing, so I used to eat one meal with our ****. (Because I am also a Stict Vegitarian for 23 years. So he with us *** meal, also vegetarian, remind, to become a long-term vegetarian, first of all, their own vegetarian do not partiality, what all eat all the nutrients must be sufficient, this aspect I think you should be very clear.) , because the dog's teeth sharp teeth number is more, so they also prefer hard and crunchy food, our family pudding, the favorite is corn, cabbage (or cabbage) he also like, mainly because there is to gnaw. Nuts they also like. If I've said it before, they just need love, so they are happiest when they get to eat at the same time as you. So, in addition to giving him his own bowl, please keep an eye on him from time to time, he will look at you and you can give him some more of the food you are eating as a love reward, they will be so happy. (By the way, pay special attention, although he ate the same food with us, but please pay attention to not too salty, I think if you are also eating light people, it should be no problem, otherwise it is best to go through a little bit of water, too much salt food, they ate will lose hair)
The other meal, we still according to the veterinarian's instructions and say, give them dog food (generally have to fill in the inside of some of them need to increase the special nutrients) Part, after all, they are not human beings, have their own physiological system oh), there is a special block of vegetarian dog food for sale, please go online to check, (because of the obstacles to know the protocols, so I can not tell you the brand here, but the Internet to find out).
Please note that this meal is usually you put in his special food containers (usually with the water dispenser together), they will not like, because one of their own to eat uninterested, so you have to accompany him, talk to you, of course, the dog food than is really not good, but for his health, you'd better let him eat.
Additionally, a tip, because we have a vegetarian and non-vegetarian in our family, if they must feed meat or meat to your dog, please communicate with them, because they are more inclined to meat by nature (you see their teeth know), please do not feed your dog arbitrarily. This will interfere with their other meal (vegetarian dog food intake, dog food is important, even if it is human meat or meat it is not okay. Again, dogs are dogs and humans are humans, the physiological systems are different), they will go days without eating dog food, and if they feed meat food like that on a regular basis, then basically the dog will become a complete meat eater. You really shouldn't cook meat food to feed them yourself, even if you feed them only non-vegetarian dog food, you won't be able to stand the smell and their feces. It will also affect your relationship with your dog. So communicate with your non-vegetarian family members or friends and do not feed them randomly. In addition, pay attention to if it is a large dog, often to go out for a walk, if there is a road others abandoned food, please do not let them eat, if he went to smell, we must be a little more strict, face to face with you to say NO. (Even said a few times), they will remember. Dogs are very spiritual. Foreign experts have put forward research reports - the general public think that dogs do not understand the human language, in fact, not, they are able to speak through your audio easier and in-depth understanding of the things you want to express, and even the inner feelings, so they have them there is a point to pay attention to, do not lightly tantrums, do not lie to them.
Speaking of which. I'll talk about how to get along with them in passing.
In fact, especially the pet dog, really God gave us the best gift, but also you cultivate love the best mentor. They are innocent and sensitive. All your interactions with him, if it is full of love, you will immediately feel several times the reply of love, his life is only you, will not lie to you, will not betray. So, relatively between you and him, you can really feel the "truth, goodness and beauty/'. The more interactions you have, the more positive energy you get lovingly, and the more positively you will add to your social relationships and interactions with human beings.
Treat him with sincerity. He understands everything, he just can't tell you in human language. If you love them with all your heart, you will hear their response, it's true that "Zen doesn't need words" - it's a way of communicating with your heart without words.
Of course, that's why I wanted you to seriously consider getting a dog in the first place, because, since it's no longer an agrarian society, you'll probably often have to leave them alone at home for the day.
Just the other day I watched a video called "What is your dog doing when you're not home?" I was so moved by that. Since, I am in my own company, the pudding can be around all day, and if you have a 9-5 job, it's a good liter of time for them to wait. So when you get home, make sure you hug him. Give him lots of love and thank him for waiting so patiently for you.
Our pudding is more intimate with us, eating together and sleeping together. So cleaning should be more thoughtful, which is also to your personal hygiene and health to pay attention to. Especially they always lose more hair every season.
Internal and external deworming must be to do, vaccination must be played, bathing because their skin tissue is different from ours, can not be too often bathed, so you can give him some clean sand, in addition to often help him with a wet cloth to wipe, pay attention to their feet, it is necessary to keep clear and dry. This way he clean, you healthy, but also can often hold and play together.
Linlin, too much. What a wonderful thing in life to have him.
Everything is "true love". Use that as a starting point. You can ask again if you have questions.
However, one final word of caution. Since I assume you're a vegetarian, the love is definitely there, but a dog's life is only 15 years at most, usually just 10, and he must be with him more all the time in his last days. Also, when you do pass on, be mindful of your mental preparation and heart adjustment afterwards, why wouldn't that be an important, and good, life lesson?
