Maiskolben

auf den zahlreichen Maisfeldern sind nun wieder zig Millionen Maiskolben gewachsen.

Viele Hunde lieben Maiskolben.

Aber Vorsicht! Teile des Maiskolbens sind unverdaulich. Der unverdauliche Strunk hat schon bei Hunden zum Darmverschluß geführt. Wenn Ihr Hund Maiskolben mag, dann passen Sie auf, das er nicht ganze Teile davon unzerkaut abschluckt. maisjpg
