Our Special Friends - Animal Words and Terms

Answer 1 is probably the most usual.
Please don't try feeding any of these other things to a dog!

A pony is a young or small horse.
A 'calf' (Answer 3) is a young cow; and we don't think that riding sheep is likely to be a very successful idea ... though somebody has probably tried!

No doubt we all know that dogs need to eat and drink, and to enjoy regular healthy exercise in the fresh air; and that they do indeed need to 'leave something behind' from time to time. Like many languages, English has plenty of other expressions to describe that. But the one we have used here should be clear enough to convey the message.
Another expression that you sometimes hear is 'Some dog has 'done its business' on the grass outside our gate.' We wonder what ways your own language might use, to refer politely to an entirely natural function. There should be no need to spend ages with your dictionary checking this; you will have plenty of other, much more important language to learn!

Young (or even new-born) cats are called 'kittens'.
You could call them 'babies' (Answer 4) but we usually only use that word for humans, unless we are joking slightly.
'Puppies' (Answer 3) are the equivalent for dogs, i.e. newborn or very young ones!

Chickens are the only birds in the list we offered you.
Some people keep a pig (since this animal, too, will eat almost anything) and eventually there will be good meat, if the people can bear to have the pig killed.
Meanwhile cows, of course ~ along with goats and possibly sheep ~ produce milk.
And we haven't mentioned rabbits ... !

Answer 3 is the only one with the right words here. Having pets should be a pleasure, but let's not pretend that it does not bring important responsibilities.

'Mouse' has an irregular plural form, 'mice'. The spelling seems to change quite a lot in the middle, but only one sound changes.

Again, all the other answers are wrong (or, at best, unhelpful).
So far as we know, it is difficult ~ and probably against the law ~ to try and put a tattoo onto an animal. Don't even think of it! (Though sooner or later, someone probably will ...)

When talking about animals, we refer to their 'fur' rather than 'hair', though we also say 'his coat is thick and black' (or whatever else it's like). The feet of cats, dogs etc. are 'paws'. ('Hoof' in Answer 4 is the hard foot such as a larger, farm animal would have.)

A bowl is quite a small container; many people believe it would not give enough space for a fish, even if the fish is quite small too. A tank (with 'square corners') is almost certainly better.
A 'pot' (Answer 2) would normally be even smaller than a bowl: the sort of container in which you might buy jam, for instance. Or it could even be a flower-pot, or at least one made of porcelain rather than glass ~ in which case the fish wouldn't get much natural light. No kind of 'pot' is really appropriate for keeping fish.
