[nagdu] muzzle question.

[Mária Orovčíková]

Hello list,
I would like to ask you for help again.
as I have said a few times my dog is trained to relieve off-leash. 
Everything was fine until now.
About a month ago someone put a sticker on each appartment complex door 
saying that people who have dogs must pick up after them. In case they 
will be seen not picking up, they will be reported to the police. All 
the same text was posted on my town Facebook page. Someone commented 
that it was written by someone who might not like dogs. Another person 
commented that people should not have dogs in this town and dogs should 
be strictly for bidden because many people let their dogs poop on the 
pavement and not pick after them. Another person then commented that 
they have seen meat and bones on the grass and they were worried it 
might be poisonous for our dogs. They think that someone has had enough 
of the mess and poops on the pavements and people not picking up after 
dogs and they will try to get rid of dogs by putting poisonous meat and 
bones around.
My dog is trained to relieve off-leash and I am so worried that he might 
eat something of the ground.
Is it possible to train 11-years-old dog to get used to a muzzle?
I have tried to put it a few times, but she did not like it at all. When 
she had it She was salivating that much and she had kind of nasty 
infection on her mounth.
Any kind of advice will be highly appreciated.
Thank you very much in advance.
With kind regards
Maria and Demi
