The RSPCA's campaign seems to have stepped up a gear. Here's what it says on its website:
We are urging retailers, farmers and consumers to all take responsibility in tackling the serious welfare concerns facing the dairy cow.
Of the two million dairy cows in the UK, the vast majority are of the Holstein breed, many of whom live with a number of serious health problems. Similarly, these cattle are possibly more inbred than many of the pedigree dog breeds.
Two of the indicators of increasing levels of inbreeding, within the national herd, are the inability to reproduce and an increasing susceptibility to disease.
They are also dogged with problems associated with lameness, mastitis (a painful inflammation of the udder), and other conditions such as bovine viral diarrhoea (BVD) and leptospirosis (a bacterial disease), which are becoming increasingly widespread.
We wouldn't treat our pets this way, so why cows?
And people may be shocked to learn that it is perfectly legal to treat a lame cow, which may involve cutting into live tissue, without the use of any pain relief.
The increasing demand for ever higher milk yields, at ever lower prices, has lead to an intensified system. A system that to many would seem completely inconsistent with the image of dairy cows happily chewing cud in the field.
These days many of our dairy cows are kept indoors for their entire lives in intensive systems, never once seeing a field, let alone able to graze.
Welfare concerns highlighted in BBC's Countryfile
John Avizienius, deputy head of farm animal science at the RSPCA, is a former herdsman.
He appeared on the BBC's rural affairs show, Countryfile, on Sunday, 10 May shedding light on these problems, alongside an eminent Cambridge professor and members of the dairy cow industry.
John said: "This is a very real problem, and one that must be tackled by everyone, from farmers and retailers to us the consumer.
"If we don't take action now we could end up milking the dairy cow to death."
If you missed Countryfile, you can still catch it on BBC iPlayer until Sunday, 17 May.

We must all work together to tackle these issues
At the moment, although some farmers have very good levels of welfare, their milk is sold for the same price as everyone else's in the supermarket.
While any work to improve welfare by the farmers and supermarkets is to be applauded, we need to work together to ensure a greater number of cows (and farmers) will benefit.
Consumer power is key
Greater consumer awareness of the issues is key. The more shoppers demand better welfare for dairy cows, and are prepared to spend a few pence more to award farmers who do invest in better standards, the quicker we will see these desperately needed changes taking place.
In the meantime, if you are concerned about the welfare of the animal that produced your milk, we would urge you to ask at your supermarkets where the milk has come from, and whether they have good standards of welfare.
