1. A soft chewable veterinary pharmaceutical product for oral administration,
wherein the soft chewable veterinary pharmaceutical product is obtainable by a process wherein the soft chewable veterinary pharmaceutical product is formed with a rotary moulding machine, comprising the steps of:
a) mixing at least one active pharmaceutical ingredient with one or more components wherein the components are dry components and liquid components to prepare a premix,
b) heating a polyethylene glycol forming agent until melting,
c) mixing the premix and the polyethylene glycol forming agent together to form a dough,
d) feeding the dough into a container connected with a rotary moulding machine; and
e) forming a soft chewable veterinary pharmaceutical product for oral administration in a rotary moulding machine,
wherein the liquid component comprises one or more oils and the polyethylene glycol forming agent is solid at room temperature and has a melting point between 45° C. and 100° C.;
wherein the temperature of the dough in step d) is between 35° C. and 45° C.; and
wherein the rotary moulding machine does not have a knockoff mechanism or a punch mechanism;
wherein the active pharmaceutical ingredient is 4-[5-(3,5-Dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazol-3-yl]-2-methyl-N-[(2,2,2-trifluoro-ethylcarbamoyl)-methyl]-benzamide; and
wherein the soft chewable veterinary pharmaceutical product has concave edges and has a weight of about 2 g or less or has a weight of more than about 10 g.
