I have 2 dogs and a flowering Rowan tree just discovered the toxicity to dogs. Can I remove berries now from branches? Will this have any effect on tree?
Removing berries within the reach of your pets should not affect the tree in any negative way. Here are a couple articles on Rowan Berry or Mountain Ash trees:

Garden Rowan Trees in full blossom have had significant amounts of branches removed and remaining blossom turned brown over night. Have the trees been damaged
It is best to prune when the tree is still dormant, in late winter. Also, never remove more than 25 to 30 percent of a tree or shrub at one time. I'm sure the tree is in shock. Keep it well watered and follow its normal care instructions and it may recover in time. A weakened tree is also more susceptible to insects and disease so watch for those. Here is more:

No. It will be best to leave it exposed. Covering may lead to infection, where as letting it be exposed to the air will help it heal as it would in nature.

The top branches are not producing leaves and the top looks like it's dead or dying. Why is this happening and why what can I do?
Unfortunately, these trees are susceptible to a range of diseases that cause this issue, as well as nutrient deficiencies and pH issues. You may need testing to know what is causing this problem.

I don’t know the name of my Rowan. I thought it was an Olympic Flame (labelled as such) but so far it hasn’t flowered so it’s hard to tell. Leaf looks similar but they didn’t start out purple. - they were green from the start. but info I’ve read recently says Olympic Flame have few side shoots. Mine is nothing but side shoots! It was new 18 months ago. And didn’t grow at all last year but this year it’s turned into a perpendicular mass of leaves. From the base to tip. Maybe they will turn into branches? I have a small garden in Gloucestershire in the SW of England. I could send an image. What to do? Can’t seem to upload photo on my ancient iPad.
It is supposed to be a small, columnar tree, but I see what you mean about no branches.
I would remove about 1/3 of the tree's branches from the bottom going up, and see if that helps. Here is more information"

I bought a 6-7ft above tree in 2019 and planted it with care in a correct position, it did not flower in 2020 and when I asked the supplier they said wait another year, I have waited and yet again it has not flowered therefore no berries. I emailed the supplier again and got no help except to look at the RHS website which I had already done and I talked to the grower but as I am not trade they would not help. I bought this specifically as I read it was a prolific flowerer but so far I have been V disappointed. Should I try feeding it in the spring - any help/advice would be much appreciated. Our soil is quite heavy but we incorporated compost ad root grow when we planted it.
It is best suited for USDA zones 3-6. Your area is outside of this zone, and may not remain cold enough for long enough during the winter to satisfy the chill requirements of the tree.
Another issue may be that your soil is too rich. High nitrogen will be very bad for the tree.
This article will offer more information on the tree:

Now there are leaves growing out of it. Could this be the start of another?
It is common for sprouts to grow on tree stumps. Fast-growing trees will often regrow into a new tree. However, the tree will likely be multi-trunked with long, wild branches, susceptible to storm damage.
Here is how to stop the sprouts:
