I think it is not A good idea.
People keep animals in too small A flat, this concerns particularLy 'big' LARGE
dogs, but pets need much free space. If they 'have not enough it' (niegram - DO NOT HAVE ENOUGH they feel like prisoners.
Pets need our attention and our time, (very) much time.
Many animals suffer when THE bored owner throwS THEM out from THE house onTO THE street for example 'dog whether cat' (nie, nie tak - a dog or a cat). People ARE bored by snakes, different insects, or different dangerous animals they let 'it' THEM (bo animals to l. mn) go taking THEM away outside the town. These animals become very dangerous for men because a lot of them can 'to' (niepotr) transmit very serious diseases, or even attack men.
Dogs can be very helpful in A man's life. There are men, which need dogS for their protection or to guard their house.
'Every pet's purchase' (nie, zrob to inaczej...THE purchase of every pet.. should be well thought out and we ought to anticipate any consequences
(which may arise out) of keeping pets.
