Great Dane named Zeus hold a Guiness World Record for the tallest dog, with the height 111 cm at the withers and streched height 226 cm when standing on his hind legs.
Especially because of their size, i would not recommend neither of these two dog breed to novice dog owners, because if you fail the training or socialization with dog this big, you will have a big problem. They are also not the best dogs for seniors or families with small and young babies.
Cane Corso height should be between 60 – 68 cms and weigh between 40 – 50 kg. Females are most of the time between 40 – 45 and males between 45 – 50 kgs.
Cane Corso can be described as courageous, loyal, quiet and cheerful dog. They are not only guards, they love to work and they actually were used for herding cattle and hunting big game in the past. But they do make good guards and they are very responsive and agile dogs.
The Cane Corso originated from Italy and their ancestors are the old Roman Molossians. This dog was primarily used to hunt boars and protect and their name actually means guardion or protector.

The Presa Canario needs a lot of obedience training and they need firm, strict and patient leader. They are dominant dogs and they are very suspicious towards strangers. This trait actually makes them excellent guards, but it can be the trait that makes them hard to manage.
JACK RUSSELL TERRIER SHORT DESCRIPTION:
JRT is from Great Britain. Jack Russell was developed for foxhunting. Jack Russell Terriers are always in all white coat or in white coat with black and tan markings and their height is between 10-15 inch.
Jack Russell Terrier ears are described as V-shaped and flapped forwards as in fox terriers. Jack Russell Terrier can have smooth, broken or rough coat. If you are not familiar, what broken coat is, it is a coat that is very similar to a smooth coat but has trace hair on the head, face, legs or body.
RAT TERRIER SHORT DESCRIPTION:
The AKC breed standard for Rat Terrier is saying, that their height is between 13-18 inches. There is also a miniature version of Rat Terrier, recognized by the AKC, which have standard height between 10-13 inch, so they are similarly tall as JRTs.
Rat Terrier ears are most often erect or semi-erect ears. Rat Terrier can only have a smooth coat and you can find Rat Terriers in many color combination, but one of the colors is always white. The second color can be red, apricot, chocolate, black, fawn, blue or you can also find all white Rat Terrier.
Rat Terrier, just like any other terrier is an active dog too, but definitely not as much as JRT. Some Rat Terriers are actually much calmer, than a typical terrier breeds. This can be a big advantage for some older or not so active people. Because if you will get a JRT, be prepared, that will need a lot of physical stimulation. It can be a lot of fun, but it can also be little bit difficult.
Brittish Collies are smaller with weight between 22 to 32 kgs and height between 55 and 60 cm. American Collies height is between 60 to 66 cms and weight between 27 to 34 kgs.
The official colors of Rough Collies are blue merle, tricolour or the famous Sable and White. The official breed standard states, that all white or predominately white Collies are Highly undesirable. That is another problem for American Collie lovers, because there is a lot of them in white colors.
The first Collie was imported to USA in 1897 by Allen Apgar and because his Collies started winning dog shows, other people wanted them as well. Today, Collies are very popular in USA and it is no wonder, they are excellent dogs. The American Collie head is narrower and slimer and their eyes are smaller. Those differences are not big, but definitely noticable.
