1. kunonoka nguva. Kumbomira kupfupi pakati penguva iyo muridzi paanotanga kukwenya nzvimbo yemashiripiti yembwa uye nguva iyo makumbo ake anotanga kuzununguka. Uku kunonoka kunokonzerwa nekuti zvinotora nguva kuti tsinga dzitumire chiratidzo kuburikidza nemutsipa wepelinha kusvika kuuropi uye kudzorera chiratidzo kumashure kugumbo uye kumisa kufamba.

2. Dziisa. Iyi ndiyo nguva inotora kuti gumbo riwane kukurumidza. Kufamba kwetsoka kunowanzotanga zvishoma nezvishoma uyezve kunowedzera sezvo muridzi anoramba achikwenya kana kukwesha nzvimbo yemashiripiti.

3. Kubuda kunozotevera. Izvi zvinoreva zviitiko apo kufamba kwetsoka kunoenderera mberi mushure mekunge muridzi apedza kukwenya kana kubvisa ruoko rwake. Sezvo zvichitora nguva kuti chiratidzo chisvike pagumbo uye ichiudza kuti itange kukava, chiratidzo chekuti imire haisvike ipapo ipapo.

4. Kuneta. Kukweva kwakarebesa munzvimbo imwe chete kunogona kutungamirira kune reflex kupera. Nechikonzero ichi, dzimwe nguva paw twitching inononoka uye inomira kunyangwe muridzi achiramba achikwenya chipfuyo. Iyo reflex inoda nguva yekupora uye kuita zvakare.

Kukwenya kwembwa kunogona kunzwika kusetsa, asi kwakakosha pakuzvidzivirira kwemhuka kubva kumaparasite uye inopa ruzivo rwakakosha nezvehutano hwayo hwetsinga. Ingave imbwa ichiziva izvi kana kungonakidzwa nekukweshwa panzvimbo yemashiripiti, chinhu chimwe chine chokwadi: kukwenya mudumbu mufaro mukuru kwaari.
