I'd recommend some more research into the how cows in dairy farms are treated. Your description is rather more idyllic than the reality, I think. For one, most male calves are not needed on a dairy farm, so they are either slaughtered for veal, raised as beef cattle, or euthanized at birth [1]. Whether this matter to you depends on where you stand on vegetarianism of course, and anyway the issues with the wellfare of meat herds is not what I wanted to discuss.
The dairy cows are also not quite so happy, I think. Mastitis is a potentially fatal disease of the udder, usually caused by bacteria entering the teat; many of the practices on a dairy farm make this far more likely, and while of course the farmers are doing all they can to stop it, it is still one of the biggest issues in the industry, and it seems that some level of mastitis is expected in all dairy herds [2]. It is perhaps a side note to the animal wellfare aspect, but the use of antibiotics is a big part of the mitigations, and seems to be administered as a matter of course; this is an issue because it promotes antibiotic resistance in bacteria, which has implications for humans too.
There are other wellfare issues around overwork of cows from producing much larger amounts of milk than they would to feed a calf, whether grains are a healthy food compared to grasses, and even mental health issues such as separating cows from their calves and whether they have enough access to the outdoors.
I've tried to select links that are balanced and non-hyperbolic, but it's tricky to do. Like I said, I recommend more research but try not to be too turned off the hyperbolic articles on both sides. Articles from vegans are often under-researched and manipulative, but if you dig around you'll find that many of the issues they discuss are real. On the other hand, farmers are of course not animal hating devils and so write to defend themselves and their livelihood, but they can often go the other way and underplay the issues that are there.
And finally, animal wellfare is not the only argument for veganism, because livestock has an environmental impact comparable to the transport industry [3].
