The pet adoption plans come as a poll carried out for Rai 3 television at the weekend showed Forza Italia had slipped into third place behind the centre-left Democratic Party and the anti-establishment Five Star Movement.
With Mr Berlusconi no longer to sit in parliament thanks to his definitive tax fraud conviction, Forza Italia appears to be struggling as Berlusconi loyalists fight it out with more pragmatic figures to determine the future of the party.
Adding to his woes, judges in Milan will in the next few weeks decide where Mr Berlusconi does his 12-month community service, as punishment for tax evasion. He is also on trial for bribing a pimp and drug dealer, and has the Rubygate appeal to prepare for.
So far, animal rights campaigners are unimpressed by the initiative. The Italian Association for the Defence of Animals and the Environment claimed that Mr Berlusconi had understated the problem of unwanted pets in Italy.
It said there were another 750,000 dogs living wild, in addition to the 150,000 languishing in kennels.
"We need concrete measures. Mr Berlusconi could come and do some dog sitting for us," the association told La Stampa, thereby renewing its offer for the mogul to serve out his community service with them.
