Of… of… of… of… – How to bring to equilibrium?

[Tamara]

Of is a very useful and multi-purpose preposition but sometimes, while doing my essay-writing exercises, I am tempted to use of… of… of… of… and the sentence becomes rather overburdened and tangled.
At present my personal record is 4 ofs in a row but as I feel I could do more

The simplest example (just to illustrate my question on a 'good style') is with possessive form:

This is the most favourite toy of the dog of Mike[’s?] .
This is the most favourite toy of the Mike’s dog.
This is Mike’s dog’s favourite toy. (or, maybe 'adjective’s first' and it should be: This is the most favourite Mike’s dog’s toy. ?)

Which is better - in this particular case?
How much 'of in-a-row' do you use normally - two? three? ? When speaking? When writing (...formally, informally) ?
Could you generally recommend me a rule of thumb to follow it and not to overburden my sentences?

Hi Tamara

I'd definitely prefer This is Mike’s dog’s favourite toy.
The other sentences simply make it sound like you don't know how to use the possessive "'s".

By the way, you shouldn't say "recommend me". I'd simply omit the "me" in your sentence.
You only need to include that kind of information if people won't otherwise know who receives the recommendation. And then you need to say "to me" (to us, to him, etc.).
Jane recommended that hotel to him.

Hi Amy! Hi Tamara!

This reminds me to fetch away my wife?s dog?s friend?s toy?s rests.

Oh, yes. Now I have a new route to go… and new challenge

Thank you, Amy, for your recommendation to me concerning / (could I use of here? ) use of 'recommend to me'

But does it mean that She recommended me a good dictionary. is not correct?

Amy, I could’t put my head for cutting it off for wide use of the above in Britain, but definitely I hear
What would you recommend me [to buy,..]? exactly. Quite often and not only in shops.
